# cat /devcg/devices.list

# cat /devcg/devices.list

a 0:0 rwm
This is odd and maybe confusing. With this patch, writing 'a' to
devices.allow will add 'a *:* rwm' to the whitelist.
Also a few fixes and updates to the document.

(timers)
This patch allows torturing RCU from irq handlers (timers, in this case).
A new module parameter irqreader enables such additional torturing,
and is enabled by default. Variants of RCU that do not tolerate readers
being called from irq handlers (e.g., SRCU) ignore irqreader.

This patch re-institutes the ability to build rcutorture directly into
the Linux kernel. The reason that this capability was removed was that
this could result in your kernel being pretty much useless, as rcutorture
would be running starting from early boot. This problem has been avoided
by (1) making rcutorture run only three seconds of every six by default,
(2) adding a CONFIG_RCU_TORTURE_TEST_RUNNABLE that permits rcutorture
to be quiesced at boot time, and (3) adding a sysctl in /proc named
/proc/sys/kernel/rcutorture_runnable that permits rcutorture to be
quiesced and unquiesced when built into the kernel.
Please note that this /proc file is -not- available when rcutorture
is built as a module. Please also note that to get the earlier
take-no-prisoners behavior, you must use the boot command line to set
rcutorture's "stutter" parameter to zero.
The rcutorture quiescing mechanism is currently quite crude: loops
in each rcutorture process that poll a global variable once per tick.
Suggestions for improvement are welcome. The default action will
be to reduce the polling rate to a few times per second.

This patch takes a step towards making rcutorture more brutal by allowing
the test to be automatically periodically paused, with the default being
to run the test for five seconds then pause for five seconds and repeat.
This behavior can be controlled using a new "stutter" module parameter, so
that "stutter=0" gives the old default behavior of running continuously.
Starting and stopping rcutorture more heavily stresses RCU's interaction
with the scheduler, as well as exercising more paths through the
grace-period detection code.
Note that the default to "shuffle_interval" has also been adjusted from
5 seconds to 3 seconds to provide varying overlap with the "stutter"
interval.
I am still unable to provoke the failures that Alexey has been seeing,
even with this patch, but will be doing a few additional things to beef
up rcutorture.

Provide documentation of the kernel-doc documentation conventions oriented
to kernel hackers.
Since I figure that there will be more people reading this
kernel-doc-nano-HOWTO.txt file who are kernel developers focused on the
rest of the kernel, than there will be readers of this file who are
documentation developers extracting that embedded kernel-doc
documentation, I have taken the liberty of making the new section added
here:
How to format kernel-doc comments
the first section of the kernel-doc-nano-HOWTO.txt file.
This first section is intended to introduce, motivate and provide basic
usage of the kernel-doc mechanism for kernel hackers developing other
portions of the kernel.

I can't think of any valid reason for ext4 to not use barriers when
they are available; I believe this is necessary for filesystem
integrity in the face of a volatile write cache on storage.
An administrator who trusts that the cache is sufficiently battery-
backed (and power supplies are sufficiently redundant, etc...)
can always turn it back off again.
SuSE has carried such a patch for ext3 for quite some time now.

Fuse allocates a separate bdi for each filesystem, and registers them
in sysfs with "MAJOR:MINOR" of sb->s_dev (st_dev). This works fine for
anon devices normally used by fuse, but can conflict with an already
registered BDI for "fuseblk" filesystems, where sb->s_dev represents a
real block device. In particularl this happens if a non-partitioned
device is being mounted.
Fix by registering with a different name for "fuseblk" filesystems.
