2011-12-16xfs: remove XFS_QMOPT_DQSUSERChristoph Hellwig1-1/+0
Just read the id 0 dquot from disk directly in xfs_qm_init_quotainfo instead of going through dqget and requiring a special flag to not add the dquot to any lists. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>
2011-12-15xfs: flatten the dquot lock orderingChristoph Hellwig1-1/+3
Introduce a new XFS_DQ_FREEING flag that tells lookup and mplist walks to skip a dquot that is beeing freed, and use this avoid the trylock on the hash and mplist locks in xfs_qm_dqreclaim_one. Also simplify xfs_dqpurge by moving the inodes to a dispose list after marking them XFS_DQ_FREEING and avoid the locker ordering constraints.

2011-12-14xfs: implement lazy removal for the dquot freelistChristoph Hellwig1-3/+1
Do not remove dquots from the freelist when we grab a reference to them in xfs_qm_dqlookup, but leave them on the freelist util scanning notices that they have a reference. This speeds up the lookup fastpath, and greatly simplifies the lock ordering constraints. Note that the same scheme is used by the VFS inode and dentry caches.

2011-12-14xfs: remove XFS_DQ_INACTIVEChristoph Hellwig1-3/+1
Free dquots when purging them during umount instead of keeping them around on the freelist in a degraded state. The out of order locking in xfs_qm_dqpurge will be removed again later in this series.

2011-12-13xfs: remove xfs_qm_syncChristoph Hellwig1-5/+0
Now that we can't have any dirty dquots around that aren't in the AIL we can get rid of the explicit dquot syncing from xfssyncd and xfs_fs_sync_fs and instead rely on AIL pushing to write out any quota updates.

2011-03-07xfs: Convert xlog_warn to new logging interfaceDave Chinner1-1/+2
Convert the xfs log operations to use the new error logging interfaces. This removes the xlog_{warn,panic} wrappers and makes almost all errors emit the device they belong to instead of just refering to "XFS".

Andi Kleen reported that gcc-4.5 gives lots of warnings for him inside the XFS code. It turned out most of them are due to the quota stubs beeing macros, and gcc now complaining about macros evaluating to 0 that are not assigned to variables.

2010-02-04xfs: kill the unused XFS_QMOPT_* flush flags V2Dave Chinner1-7/+1
dquots are never flushed asynchronously. Remove the flag and the async write support from the flush function. Make the default flush a delwri flush to make the inode flush code, which leaves the XFS_QMOPT_SYNC the only flag remaining. Convert that to use SYNC_WAIT instead, just like the inode flush code. V2: - just pass flush flags straight through Signed-off-by: Dave Chinner <david@fromorbit.com> Reviewed-by: Christoph Hellwig <hch@lst.de>

2009-12-15xfs: event tracing supportChristoph Hellwig1-0/+8
Convert the old xfs tracing support that could only be used with the out of tree kdb and xfsidbg patches to use the generic event tracer. To use it make sure CONFIG_EVENT_TRACING is enabled and then enable all xfs trace channels by: echo 1 > /sys/kernel/debug/tracing/events/xfs/enable or alternatively enable single events by just doing the same in one event subdirectory, e.g. echo 1 > /sys/kernel/debug/tracing/events/xfs/xfs_ihold/enable or set more complex filters, etc. In Documentation/trace/events.txt all this is desctribed in more detail. To reads the events do a cat /sys/kernel/debug/tracing/trace Compared to the last posting this patch converts the tracing mostly to the one tracepoint per callsite model that other users of the new tracing facility also employ. This allows a very fine-grained control of the tracing, a cleaner output of the traces and also enables the perf tool to use each tracepoint as a virtual performance counter, allowing us to e.g. count how often certain workloads git various spots in XFS. Take a look at http://lwn.net/Articles/346470/ for some examples. Also the btree tracing isn't included at all yet, as it will require additional core tracing features not in mainline yet, I plan to deliver it later. And the really nice thing about this patch is that it actually removes many lines of code while adding this nice functionality: fs/xfs/Makefile | 8 fs/xfs/linux-2.6/xfs_acl.c | 1 fs/xfs/linux-2.6/xfs_aops.c | 52 - fs/xfs/linux-2.6/xfs_aops.h | 2 fs/xfs/linux-2.6/xfs_buf.c | 117 +-- fs/xfs/linux-2.6/xfs_buf.h | 33 fs/xfs/linux-2.6/xfs_fs_subr.c | 3 fs/xfs/linux-2.6/xfs_ioctl.c | 1 fs/xfs/linux-2.6/xfs_ioctl32.c | 1 fs/xfs/linux-2.6/xfs_iops.c | 1 fs/xfs/linux-2.6/xfs_linux.h | 1 fs/xfs/linux-2.6/xfs_lrw.c | 87 -- fs/xfs/linux-2.6/xfs_lrw.h | 45 - fs/xfs/linux-2.6/xfs_super.c | 104 --- fs/xfs/linux-2.6/xfs_super.h | 7 fs/xfs/linux-2.6/xfs_sync.c | 1 fs/xfs/linux-2.6/xfs_trace.c | 75 ++ fs/xfs/linux-2.6/xfs_trace.h | 1369 +++++++++++++++++++++++++++++++++++++++++ fs/xfs/linux-2.6/xfs_vnode.h | 4 fs/xfs/quota/xfs_dquot.c | 110 --- fs/xfs/quota/xfs_dquot.h | 21 fs/xfs/quota/xfs_qm.c | 40 - fs/xfs/quota/xfs_qm_syscalls.c | 4 fs/xfs/support/ktrace.c | 323 --------- fs/xfs/support/ktrace.h | 85 -- fs/xfs/xfs.h | 16 fs/xfs/xfs_ag.h | 14 fs/xfs/xfs_alloc.c | 230 +----- fs/xfs/xfs_alloc.h | 27 fs/xfs/xfs_alloc_btree.c | 1 fs/xfs/xfs_attr.c | 107 --- fs/xfs/xfs_attr.h | 10 fs/xfs/xfs_attr_leaf.c | 14 fs/xfs/xfs_attr_sf.h | 40 - fs/xfs/xfs_bmap.c | 507 +++------------ fs/xfs/xfs_bmap.h | 49 - fs/xfs/xfs_bmap_btree.c | 6 fs/xfs/xfs_btree.c | 5 fs/xfs/xfs_btree_trace.h | 17 fs/xfs/xfs_buf_item.c | 87 -- fs/xfs/xfs_buf_item.h | 20 fs/xfs/xfs_da_btree.c | 3 fs/xfs/xfs_da_btree.h | 7 fs/xfs/xfs_dfrag.c | 2 fs/xfs/xfs_dir2.c | 8 fs/xfs/xfs_dir2_block.c | 20 fs/xfs/xfs_dir2_leaf.c | 21 fs/xfs/xfs_dir2_node.c | 27 fs/xfs/xfs_dir2_sf.c | 26 fs/xfs/xfs_dir2_trace.c | 216 ------ fs/xfs/xfs_dir2_trace.h | 72 -- fs/xfs/xfs_filestream.c | 8 fs/xfs/xfs_fsops.c | 2 fs/xfs/xfs_iget.c | 111 --- fs/xfs/xfs_inode.c | 67 -- fs/xfs/xfs_inode.h | 76 -- fs/xfs/xfs_inode_item.c | 5 fs/xfs/xfs_iomap.c | 85 -- fs/xfs/xfs_iomap.h | 8 fs/xfs/xfs_log.c | 181 +---- fs/xfs/xfs_log_priv.h | 20 fs/xfs/xfs_log_recover.c | 1 fs/xfs/xfs_mount.c | 2 fs/xfs/xfs_quota.h | 8 fs/xfs/xfs_rename.c | 1 fs/xfs/xfs_rtalloc.c | 1 fs/xfs/xfs_rw.c | 3 fs/xfs/xfs_trans.h | 47 + fs/xfs/xfs_trans_buf.c | 62 - fs/xfs/xfs_vnodeops.c | 8 70 files changed, 2151 insertions(+), 2592 deletions(-) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>

2009-06-08xfs: kill xfs_qmopsChristoph Hellwig1-60/+62
Kill the quota ops function vector and replace it with direct calls or stubs in the CONFIG_XFS_QUOTA=n case. Make sure we check XFS_IS_QUOTA_RUNNING in the right spots. We can remove the number of those checks because the XFS_TRANS_DQ_DIRTY flag can't be set otherwise. This brings us back closer to the way this code worked in IRIX and earlier Linux versions, but we keep a lot of the more useful factoring of common code. Eventually we should also kill xfs_qm_bhv.c, but that's left for a later patch. Reduces the size of the source code by about 250 lines and the size of XFS module by about 1.5 kilobytes with quotas enabled: text data bss dec hex filename 615957 2960 3848 622765 980ad fs/xfs/xfs.o 617231 3152 3848 624231 98667 fs/xfs/xfs.o.old Fallout: - xfs_qm_dqattach is split into xfs_qm_dqattach_locked which expects the inode locked and xfs_qm_dqattach which does the locking around it, thus removing XFS_QMOPT_ILOCKED.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
