* GFS2: quota allows exceeding hard limitAbhijith Das2011-03-091-1/+7
| | | | | | | | | | | | | | | | | Immediately after being synced to disk, cached quotas are zeroed out and a subsequent access of the cached quotas results in incorrect zero values. This meant that gfs2 assumed the actual usage to be the zero (or near-zero) usage values it found in the cached quotas and comparison against warn/limits never triggered a quota violation. This patch adds a new flag QDF_REFRESH that is set after a sync so that the cached quotas are forcefully refreshed from disk on a subsequent access on seeing this flag set.

* | mm: add context argument to shrinker callbackDave Chinner2010-07-191-1/+1
|/ | | | | | | | | | | | The current shrinker implementation requires the registered callback to have global state to work from. This makes it difficult to shrink caches that are not global (e.g. per-filesystem caches).

* GFS2: Fix writing to non-page aligned gfs2_quota structuresAbhijith Das2010-05-101-25/+61
| | | | | | | | | | | | | | | | | This is the upstream fix for this bug. This patch differs from the RHEL5 fix (Red Hat bz #555754) which simply writes to the 8-byte value field of the quota. In upstream quota code, we're required to write the entire quota (88 bytes) which can be split across a page boundary. We check for such quotas, and read/write the two parts from/to the corresponding pages holding these parts. With this patch, I don't see the bug anymore using the reproducer in Red Hat bz 555754.

Move it into vfs_quota_sync and add a wait parameter to ->quota_sync to tell if we need it or not.

Setting setting statfs_quantum to 0 will also turn on the statfs_slow tunable. statfs_percent accepts an integer between 0 and 100. Numbers between 1 and 100 will cause GFS2 to do any early sync when the local number of blocks free changes by at least statfs_percent from the totoal number of blocks free. Setting statfs_percent to 0 disables this. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* GFS2: Merge lock_dlm module into GFS2Steven Whitehouse2009-03-241-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is the big patch that I've been working on for some time now. There are many reasons for wanting to make this change such as: o Reducing overhead by eliminating duplicated fields between structures o Simplifcation of the code (reduces the code size by a fair bit) o The locking interface is now the DLM interface itself as proposed some time ago. o Fewer lookups of glocks when processing replies from the DLM o Fewer memory allocations/deallocations for each glock o Scope to do further optimisations in the future (but this patch is more than big enough for now!) Please note that (a) this patch relates to the lock_dlm module and not the DLM itself, that is still a separate module; and (b) that we retain the ability to build GFS2 as a standalone single node filesystem with out requiring the DLM. This patch needs a lot of testing, hence my keeping it I restarted my -git tree after the last merge window. That way, this has the maximum exposure before its merged. This is (modulo a few minor bug fixes) the same patch that I've been posting on and off the the last three months and its passed a number of different tests so far.

* GFS2: Fix "truncate in progress" hangSteven Whitehouse2009-01-051-1/+30
| | | | | | | | | | | | | | | | | | | | | | | Following on from the recent clean up of gfs2_quotad, this patch moves the processing of "truncate in progress" inodes from the glock workqueue into gfs2_quotad. This fixes a hang due to the "truncate in progress" processing requiring glocks in order to complete. It might seem odd to use gfs2_quotad for this particular item, but we have to use a pre-existing thread since creating a thread implies a GFP_KERNEL memory allocation which is not allowed from the glock workqueue context. Of the existing threads, gfs2_logd and gfs2_recoverd may deadlock if used for this operation. gfs2_scand and gfs2_glockd are both scheduled for removal at some (hopefully not too distant) future point. That leaves only gfs2_quotad whose workload is generally fairly light and is easily adapted for this extra task. Also, as a result of this change, it opens the way for a future patch to make the reading of the inode's information asynchronous with respect to the glock workqueue, which is another improvement that has been on the list for some time now.

* GFS2: Clean up & move gfs2_quotadSteven Whitehouse2009-01-051-6/+70
| | | | | | | | | | | | | | | | | | | | | | This patch is a clean up of gfs2_quotad prior to giving it an extra job to do in addition to the current portfolio of updating the quota and statfs information from time to time. As a result it has been moved into quota.c allowing one of the functions it calls to be made static. Also the clean up allows the two existing functions to have separate timeouts and also to coexist with its future role of dealing with the "truncate in progress" inode flag. The (pointless) setting of gfs2_quotad_secs is removed since we arrange to only wake up quotad when one of the two timers expires. In addition the struct gfs2_quota_data is moved into a slab cache, mainly for easier debugging. It should also be possible to use a shrinker in the future, rather than the current scheme of scanning the quota data entries from time to time. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

| | | | | | | | | | | | | | | | | It is possible to reduce the size of GFS2 inodes by taking the i_alloc structure out of the gfs2_inode. This patch allocates the i_alloc structure whenever its needed, and frees it afterward. This decreases the amount of low memory we use at the expense of requiring a memory allocation for each page or partial page that we write. A quick test with postmark shows that the overhead is not measurable and I also note that OCFS2 use the same approach. In the future I'd like to solve the problem by shrinking down the size of the members of the i_alloc structure, but for now, this reduces the immediate problem of using too much low-memory on x86 and doesn't add too much overhead.

* [GFS2] Fix sign problem in quota/statfs and cleanup _host structuresSteven Whitehouse2007-07-091-1/+41
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes some sign issues which were accidentally introduced into the quota & statfs code during the endianess annotation process. Also included is a general clean up which moves all of the _host structures out of gfs2_ondisk.h (where they should not have been to start with) and into the places where they are actually used (often only one place). Also those _host structures which are not required any more are removed entirely (which is the eventual plan for all of them). The conversion routines from ondisk.c are also moved into the places where they are actually used, which for almost every one, was just one single place, so all those are now static functions. This also cleans up the end of gfs2_ondisk.h which no longer needs the #ifdef __KERNEL__. The net result is a reduction of about 100 lines of code, many functions now marked static plus the bug fixes as mentioned above. For good measure I ran the code through sparse after making these changes to check that there are no warnings generated.
