2008-04-18ocfs2: Add inode stealing for ocfs2_reserve_new_inodeTao Ma
Inode allocation is modified to look in other nodes allocators during extreme out of space situations. We retry our own slot when space is freed back to the global bitmap, or whenever we've allocated more than 1024 inodes from another slot.

2008-04-18ocfs2: Add the USERSPACE_STACK incompat bit.Joel Becker
The filesystem gains the USERSPACE_STACK incomat bit and the s_cluster_info field on the superblock. When a userspace stack is in use, the name of the stack is stored on-disk for mount-time verification. The "cluster_stack" option is added to mount(2) processing. The mount process needs to pass the matching stack name. If the passed name and the on-disk name do not match, the mount is failed. When using the classic o2cb stack, the incompat bit is *not* set and no mount option is used other than the usual heartbeat=local. Thus, the filesystem is compatible with older tools.

2008-04-18ocfs2: Break out stackglue into modules.Joel Becker
We define the ocfs2_stack_plugin structure to represent a stack driver. The o2cb stack code is split into stack_o2cb.c. This becomes the ocfs2_stack_o2cb.ko module. The stackglue generic functions are similarly split into the ocfs2_stackglue.ko module. This module now provides an interface to register drivers. The ocfs2_stack_o2cb driver registers itself. As part of this interface, ocfs2_stackglue can load drivers on demand. This is accomplished in ocfs2_cluster_connect(). ocfs2_cluster_disconnect() is now notified when a _hangup() is pending. If a hangup is pending, it will not release the driver module and will let _hangup() do that. Signed-off-by: Joel Becker <joel.becker@oracle.com>

2008-04-18ocfs2: Fill node number during cluster stack initMark Fasheh
It doesn't make sense to query for a node number before connecting to the cluster stack. This should be safe to do because node_num is only just printed, and we're actually only moving the setting of node num a small amount further in the mount process.

2008-04-18ocfs2: Move o2hb functionality into the stack glue.Joel Becker
The last bit of classic stack used directly in ocfs2 code is o2hb. Specifically, the check for heartbeat during mount and the call to ocfs2_hb_ctl during unmount. We create an extra API, ocfs2_cluster_hangup(), to encapsulate the call to ocfs2_hb_ctl. Other stacks will just leave hangup() empty. The check for heartbeat is moved into ocfs2_cluster_connect(). It will be matched by a similar check for other stacks. With this change, only stackglue.c includes cluster/ headers.

2008-04-18ocfs2: Abstract out node number queries.Joel Becker
ocfs2 asks the cluster stack for the local node's node number for two reasons; to fill the slot map and to print it. While the slot map isn't necessary for userspace cluster stacks, the printing is very nice for debugging. Thus we add ocfs2_cluster_this_node() as a generic API to get this value. It is anticipated that the slot map will not be used under a userspace cluster stack, so validity checks of the node num only need to exist in the slot map code. Otherwise, it just gets used and printed as an opaque value.

2008-04-18ocfs2: Introduce the new ocfs2_cluster_connect/disconnect() API.Joel Becker
This step introduces a cluster stack agnostic API for initializing and exiting. fs/ocfs2/dlmglue.c no longer uses o2cb/o2dlm knowledge to connect to the stack. It is all handled in stackglue.c. heartbeat.c no longer needs to know how it gets called. ocfs2_do_node_down() is now a clean recovery trigger. The big gotcha is the ordering of initializations and de-initializations done underneath ocfs2_cluster_connect(). ocfs2_dlm_init() used to do all o2dlm initialization in one block. Thus, the o2dlm functionality of ocfs2_cluster_connect() is very straightforward. ocfs2_dlm_shutdown(), however, did a few things between de-registration of the eviction callback and actually shutting down the domain. Now de-registration and shutdown of the domain are wrapped within the single ocfs2_cluster_disconnect() call. I've checked the code paths to make sure we can safely tear down things in ocfs2_dlm_shutdown() before calling ocfs2_cluster_disconnect(). The filesystem has already set itself to ignore the callback. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2008-04-18ocfs2: Separate out dlm lock functions.Joel Becker
This is the first in a series of patches to isolate ocfs2 from the underlying cluster stack. Here we wrap the dlm locking functions with ocfs2-specific calls. Because ocfs2 always uses the same dlm lock status callbacks, we can eliminate the callbacks from the filesystem visible functions.

2008-04-18ocfs2: Change the recovery map to an array of node numbers.Joel Becker
The old recovery map was a bitmap of node numbers. This was sufficient for the maximum node number of 254. Going forward, we want node numbers to be UINT32. Thus, we need a new recovery map. Note that we can't keep track of slots here. We must write down the node number to recovery *before* we get the locks needed to convert a node number into a slot number. The recovery map is now an array of unsigned ints, max_slots in size. It moves to journal.c with the rest of recovery. Because it needs to be initialized, we move all of recovery initialization into a new function, ocfs2_recovery_init(). This actually cleans up ocfs2_initialize_super() a little as well. Following on, recovery cleaup becomes part of ocfs2_recovery_exit(). A number of node map functions are rendered obsolete and are removed. Finally, waiting on recovery is wrapped in a function rather than naked checks on the recovery_event. This is a cleanup from Mark.

2008-04-18ocfs2: Move slot map access into slot_map.cMark Fasheh
journal.c and dlmglue.c would refresh the slot map by hand. Instead, have the update and clear functions do the work inside slot_map.c.

2008-02-06ocfs2: Negotiate locking protocol versions.Joel Becker
Currently, when ocfs2 nodes connect via TCP, they advertise their compatibility level. If the versions do not match, two nodes cannot speak to each other and they disconnect. As a result, this provides no forward or backwards compatibility. This patch implements a simple protocol negotiation at the dlm level by introducing a major/minor version number scheme for entities that communicate. Specifically, o2dlm has a major/minor version for interaction with o2dlm on other nodes, and ocfs2 itself has a major/minor version for interacting with the filesystem on other nodes. This will allow rolling upgrades of ocfs2 clusters when changes to the locking or network protocols can be done in a backwards compatible manner. In those cases, only the minor number is changed and the negotatied protocol minor is returned from dlm join. In the far less likely event that a required protocol change makes backwards compatibility impossible, we simply bump the major number.

2008-01-25ocfs2: Local alloc window size changeable via mount optionSunil Mushran
Local alloc is a performance optimization in ocfs2 in which a node takes a window of bits from the global bitmap and then uses that for all small local allocations. This window size is fixed to 8MB currently. This patch allows users to specify the window size in MB including disabling it by passing in 0. If the number specified is too large, the fs will use the default value of 8MB. mount -o localalloc=X /dev/sdX /mntpoint Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2008-01-25ocfs2: Initalize bitmap_cpg of ocfs2_super to be the maximum.Tao Ma
This value is initialized from global_bitmap->id2.i_chain.cl_cpg. If there is only 1 group, it will be equal to the total clusters in the volume. So as for online resize, it should change for all the nodes in the cluster. It isn't easy and there is no corresponding lock for it. bitmap_cpg is only used in 2 areas: 1. Check whether the suballoc is too large for us to allocate from the global bitmap, so it is little used. And now the suballoc size is 2048, it rarely meet this situation and the check is almost useless. 2. Calculate which group a cluster belongs to. We use it during truncate to figure out which cluster group an extent belongs too. But we should be OK if we increase it though as the cluster group calculated shouldn't change and we only ever have a small bitmap_cpg on file systems with a single cluster group.

2008-01-25ocfs2: Remove data locksMark Fasheh
The meta lock now covers both meta data and data, so this just removes the now-redundant data lock. Combining locks saves us a round of lock mastery per inode and one less lock to ping between nodes during read/write. We don't lose much - since meta locks were always held before a data lock (and at the same level) ordered writeout mode (the default) ensured that flushing for the meta data lock also pushed out data anyways.

The node maps that are set/unset by these votes are no longer relevant, thus we can remove the mount and umount votes. Since those are the last two remaining votes, we can also remove the entire vote infrastructure.

2007-09-11[PATCH] ocfs2: fix mount option parsingTiger Yang
For some mount option types, ocfs2_parse_options() will try to access sb->s_fs_info to get at the ocfs2 private superblock. Unfortunately, that hasn't been allocated yet and will cause a kernel crash. Fix this by storing options in a struct which can then get pushed into the ocfs2_super once it's been allocated later.

We re-use the RESVSP/UNRESVSP ioctls from xfs which allow the user to allocate and deallocate regions to a file without zeroing data or changing i_size. Though renamed, the structure passed in from user is identical to struct xfs_flock64. The three fields that are actually used right now are l_whence, l_start and l_len.

2007-05-07slab allocators: Remove SLAB_DEBUG_INITIAL flagChristoph Lameter
I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by SLAB. I think its purpose was to have a callback after an object has been freed to verify that the state is the constructor state again? The callback is performed before each freeing of an object. I would think that it is much easier to check the object state manually before the free. That also places the check near the code object manipulation of the object. Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was compiled with SLAB debugging on. If there would be code in a constructor handling SLAB_DEBUG_INITIAL then it would have to be conditional on SLAB_DEBUG otherwise it would just be dead code. But there is no such code in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real use of, difficult to understand and there are easier ways to accomplish the same effect (i.e. add debug code before kfree). There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be clear in fs inode caches. Remove the pointless checks (they would even be pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors. This is the last slab flag that SLUB did not support.

2007-04-26ocfs2: Cache extent recordsMark Fasheh
The extent map code was ripped out earlier because of an inability to deal with holes. This patch adds back a simpler caching scheme requiring far less code. Our old extent map caching was designed back when meta data block caching in Ocfs2 didn't work very well, resulting in many disk reads. These days our metadata caching is much better, resulting in no un-necessary disk reads. As a result, extent caching doesn't have to be as fancy, nor does it have to cache as many extents. Keeping the last 3 extents seen should be sufficient to give us a small performance boost on some streaming workloads. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2007-04-26ocfs2: temporarily remove extent map cachingMark Fasheh
The code in extent_map.c is not prepared to deal with a subtree being rotated between lookups. This can happen when filling holes in sparse files.

Ocfs2 currently does cluster-wide node messaging to check the open state of an inode during delete.
