There is a potential race in the inode deallocation code if two
nodes try to deallocate the same inode at the same time. Most of
the issue is solved by the iopen locking. There is still a small
window which is not covered by the iopen lock. This patches fixes
that and also makes the deallocation code more robust in the face of
any errors in the rgrp bitmaps, or erroneous iopen callbacks from
other nodes.
This does introduce one extra disk read, but that is generally not
an issue since its the same block that must be written to later
in the deallocation process. The total disk accesses therefore stay
the same,

The inum structure used throughout GFS2 has two fields. One
no_addr is the disk block number of the inode in question and
is used everywhere as the inode number. The other, no_formal_ino,
is used only as the generation number for NFS.
Historically the no_formal_ino field was set using a complicated
system of one global and one per-node file containing inode numbers
in order to ensure that each no_formal_ino was unique. Also this
code made no provision for what would happen when eventually the
(64 bit) numbers ran out. Now I know that is pretty unlikely to
happen given the large space of numbers, but it is possible
nevertheless.
The only guarantee required for no_formal_ino is that, for any
single inode, the same number doesn't get reused too quickly.
We already have a generation number which is kept in the inode
and initialised from a counter in the resource group (almost
no overhead, since we have to touch the resource group anyway
in order to allocate an inode in the first place). Aside from
ensuring that we never use the value 0 in the no_formal_ino
field, we can use that counter directly.
As a result of that change, we lose about 200 lines of code and
also gain about 10 creates/sec on the postmark benchmark (on
my test machine).

Use the more conventional name for the extended attribute
support code. Update all the places which care.
Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
|

This has been on my list for some time. We need to change the way
in which we handle extended attributes to allow faster file creation
times (by reducing the number of transactions required) and the
extended attribute code is the main obstacle to this.
In addition to that, the VFS provides a way to demultiplex the xattr
calls which we ought to be using, rather than rolling our own. This
patch changes the GFS2 code to use that VFS feature and as a result
the code shrinks by a couple of hundred lines or so, and becomes
easier to read.
I'm planning on doing further clean up work in this area, but this
patch is a good start. The cleaned up code also uses the more usual
"xattr" shorthand, I plan to eliminate the use of "eattr" eventually
and in the mean time it serves as a flag as to which bits of the code
have been updated.

This patch adds "-o errors=panic" and "-o errors=withdraw" to the
gfs2 mount options. The "errors=withdraw" option is today's
current behaviour, meaning to withdraw from the file system if a
non-serious gfs2 error occurs. The new "errors=panic" option
tells gfs2 to force a kernel panic if a non-serious gfs2 file
system error occurs. This may be useful, for example, where
fabric-level fencing is used that has no way to reboot (such as
fence_scsi).

this patch is for the same problem that Benjamin Marzinski fixes at commit
b94a170e96dc416828af9d350ae2e34b70ae7347
quotation of the original problem:
---cut here---
When a file is deleted from a gfs2 filesystem on one node, a dcache
entry for it may still exist on other nodes in the cluster. If this
happens, gfs2 will be unable to free this file on disk. Because of this,
it's possible to have a gfs2 filesystem with no files on it and no free
space. With this patch, when a node receives a callback notifying it
that the file is being deleted on another node, it schedules a new
workqueue thread to remove the file's dcache entry.
---end cut---
after applying Benjamin's patch, I think there is still a case in which the disk
inode remains even when "no space" is hit. the case is that when running
d_prune_aliases() against the inode, there are one or more dentries(aliases)
which have reference count number > 0. in this case the dentries won't be pruned.
and even later, the reference count becomes to 0, the dentries can still be
cached in memory. unfortunately, no callback come again, things come back to
the state before the callback runs. thus the on disk inode remains there until
in memoryinode is removed for some other reason(shrinking inode cache or unmount
the volume..).
this patch is to remove those dentries when their reference count becomes to 0 and
the inode is deleted by remote node. for implementation, gfs2_dentry_delete() is
added as dentry_operations.d_delete. the function returns true when the inode is
deleted by remote node. in dput(), gfs2_dentry_delete() is called and since it
returns true, the dentry is unhashed from dcache and then removed. when all dentries
are removed, the in memory inode get removed so that the on disk inode is freed.

We already have an offline uevent (used when a withdraw occurs)
but no online uevent. This adds an online uevent so that userspace
will be able to detect a successful mount by means other than
not receiving a remove event after the add & recovery (change)
uevents.
It has also been added to the remount path as well - we can't use
a change uevent there as older GFS2 userspace acts on change uevents
according to the state that it thinks the fs is in, so we can't
easily add any new ones.

The triggered field of struct poll_wqueues introduced in commit
5f820f648c92a5ecc771a96b3c29aa6e90013bba ("poll: allow f_op->poll to
sleep").
It was first set to 1 in pollwake() (now __pollwake() ), tested and
later set to 0 in poll_schedule_timeout(), but not initialized before.
As a result when the process needs to sleep, triggered was likely to be
non-zero even if pollwake() is not called before the first
poll_schedule_timeout(), meaning schedule_hrtimeout_range() would not be
called and an extra loop calling all ->poll() would be done.
This patch initialize triggered to 0 in poll_initwait() so the ->poll()
are not called twice before the process goes to sleep when it needs to.

properly
This patch changes most frontend drivers to allocate their state structure via
kzalloc and not kmalloc. This is done to properly initialize the
embedded "struct dvb_frontend frontend" field, that they all have.
The visible effect of this struct being uninitalized is, that the member "id"
that is used to set the name of kernel thread is totally random.
Some board drivers (for example cx88-dvb) set this "id" via
videobuf_dvb_alloc_frontend but most do not.
So I at least get random id values for saa7134, flexcop and ttpci based cards.
It looks like this in dmesg:
DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S)
The related kernel thread then also gets a strange name
like "kdvb-ad-1-fe--1".

The v4l core supplies default handlers for G_STD and G_PARM. However, both
default handlers are buggy.
This patch fixes the following:
1) If no g_std is supplied and current_norm == 0, then this driver does not
support TV video standards (e.g. a radio or webcam driver). Return
-EINVAL. This ensures that there is no bogus VIDIOC_G_STD support for
such drivers.
2) The default VIDIOC_G_PARM handler used current_norm instead of first
checking if the driver supported g_std and calling that to get the norm.
It also didn't check if current_norm was 0, since in that case the driver
does not support TV standards (or no standard was set at all) and the
default handler should return -EINVAL.
Note that I am very unhappy with these default handlers: I think they
basically behave like some very strange and unexpected side-effect.

Drivers should either set current_norm or supply a g_std callback.
The hdpvr driver does neither. Since it initializes to a 60 Hz format

Register 0x13 seems to be a sort of image control, maybe gamma, white
level or black level. Lower values produce better images, while higher
values increases the contrast and shifts colors to green. 0xff produces
a black image. This register is not Silvercrest-specific, so its code
should be moved to a better place.
If this register is left alone, a random value can be found at the
register, producing weird results.
While here, let's remove register 0x0d, as it had no noticed effect at
the image.

Silvercrest mt9v011 sensor produces a 640x480 image. However,
previously, the code were getting only half of the lines and merging two
consecutive frames to "produce" a 640x480 image.
With the addition of progressive mode, now em28xx is working with a full
image. However, when the number of lines is bigger than 240, the
beginning of some odd lines are filled with blank.
After lots of testing, and physically checking the device for a Xtal, it
was noticed experimentally that mt9v011 is using em28xx XCLK as its
clock. Due to that, changing XCLK value changes the maximum speed of the
stream.
At the tests, it were possible to produce up to 32 fps, using a 30 MHz
XCLK. However, at that rate, the artifacts happen even at 320x240. Lower
values of XCLK produces artifacts only at 640x480.
At some values of xclk (for example XCLKK = 6 MHz, 640x480), it is
possible to see an invalid sucession of artifacts with this pattern:
.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
(where the dots represent the blanked pixels)
So, it seems that a waveform in the format of a ramp is interferring at
the image.
The cause of this interference is currently unknown. Some possibilities
are:
- electrical interference (maybe this device is broken?);
- some issue at mt9v011 programming;
- some bug at em28xx chip.
So, for now, let's be conservative and use a value of XCLK that we know
for sure that it won't cause artifacts.
As I'm waiting for more of such devices with different em28xx chipset
revisions, I'll have the opportunity to double check the issue with
other pieces of hardware.
Later patches can vary XCLK depending on the vertical resolutions, if a
proper fix is not discovered.

Due to historical reasons, em28xx driver gets two consecutive frames and
fold them into an unique framing, doing interlacing. While this works
fine for TV images, this produces two bad effects with webcams:
1) webcam images are progressive. Merging two consecutive images produce
interlacing artifacts on the image;
2) since the driver needs to get two frames, it reduces the maximum
frame rate by two.

A user discovered that the Geniatech x8000 encountered a regression when
the xc3028 power management was introduced. The xc3028 never recovers after
setting the powerdown register, which is probably because the xc3028 reset
GPIO is not properly configured. Since I do not have access to the hardware
and thus cannot determine the correct GPIO configuration, just disable xc3028

ViMicro devices
Commit 50144aeeb702ea105697ae5249f059ea3990b838 broke the Samsung NC10
netbook webcam. Instead of applying the FIX_BANDWIDTH quirk to all ViMicro
devices, list the devices explicitly.

The current GPIO configuration breaks all Hauppauge devices.
The code being removed affects Hauppauge devices only,
and is the cause of the breakage.

Currently, the VIDIOC_S_STD ioctl just returns -EINVAL regardless of
the norm passed. This patch sets cx23885_mpeg_template.tvnorms and
cx23885_mpeg_template.current_norm so that the VIDIOC_S_STD will work.
Thanks to Joseph Yasi for pointing this out, even though this particular
fix was already pushed into a development repository, merge priority of
this changeset has been escalated as a result of Joseph posting this
identical patch.
