* xfs: use generic Posix ACL codeChristoph Hellwig2009-06-107-7/+0
| | | | | | | | | | | | This patch rips out the XFS ACL handling code and uses the generic fs/posix_acl.c code instead. The ondisk format is of course left unchanged. This also introduces the same ACL caching all other Linux filesystems do by adding pointers to the acl and default acl in struct xfs_inode.

* xfs: remove SYNC_BDFLUSHChristoph Hellwig2009-06-081-23/+5
| | | | | | | | | | | | | SYNC_BDFLUSH is a leftover from IRIX and rather misnamed for todays code. Make xfs_sync_fsdata and xfs_dq_sync use the SYNC_TRYLOCK flag for not blocking on logs just as the inode sync code already does. For xfs_sync_fsdata it's a trivial 1:1 replacement, but for xfs_qm_sync I use the opportunity to decouple the non-blocking lock case from the different flushing modes, similar to the inode sync code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

With this conversion, all external access to the AIL is via the struct xfs_ail. Hence the operation and referencing of the AIL is almost entirely independent of the xfs_mount that is using it - it is now much more tightly tied to the log and the items it is tracking in the log than it is tied to the xfs_mount.

* [XFS] don't block in xfs_qm_dqflush() during async writeback.David Chinner2008-10-301-7/+5
| | | | | | | | | | | | | | | | | | | | | | Normally dquots are written back via delayed write mechanisms. They are flushed to their backing buffer by xfssyncd, which is then pushed out by either AIL or xfsbufd flushing. The flush from the xfssyncd is supposed to be non-blocking, but xfs_qm_dqflush() always waits for pinned duots, which means that it will block for the length of time it takes to do a synchronous log force. This causes unnecessary extra log I/O to be issued whenever we try to flush a busy dquot. Avoid the log forces and blocking xfssyncd by making xfs_qm_dqflush() pay attention to what type of sync it is doing when it sees a pinned dquot and not waiting when doing non-blocking flushes.

* [XFS] Catch errors when turning off quotas.David Chinner2008-04-181-3/+12
| | | | | | | | | | | | | | | When turning off quota, we need to write various transactions to the log to ensure that they are cleanly removed in the case of a crash. We need to check that the transactions hit the disk correctly. If we fail to write the final quota off transaction, we are corrupt in memory and so the only option is to shut the filesystem down at this point.

| | | | | | | | | | | | Warn to the syslog if we fail to reset the quota flags in the superblock when a quota check fails.

* [XFS] Clean up quotamount error handling.David Chinner2008-04-182-15/+15
| | | | | | | | | | | | | | xfs_qm_mount_quotas() returns an error status that is ignored. If we fail to mount quotas, we continue with quota's turned off, which is all handled inside xfs_qm_mount_quotas(). Mark it as void to indicate that errors need not be returned to the callers.

* [XFS] Check for dquot flush errorsDavid Chinner2008-04-183-7/+24
| | | | | | | | | | | | | xfs_qm_dqflush() can fail, but the return is not checked anywhere. Hence we never know if we've failed to flush a dquot to disk. Propagate the error and warn to the syslog if a flush ever fails.
