* xfs: fix variable set but not used warningsChristoph Hellwig2011-04-081-5/+0
| | | | | | | | GCC 4.6 now warnings about variables set but not used. Fix the trivially fixable warnings of this sort. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>

* xfs: kill xfs_qmopsChristoph Hellwig2009-06-081-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* xfs: get rid of indirections in the quotaops implementationChristoph Hellwig2009-02-091-4/+10
| | | | | | | | | Currently we call from the nicely abstracted linux quotaops into a ugly multiplexer just to split the calls out at the same boundary again. Rewrite the quota ops handling to remove that obfucation. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <david@fromorbit.com>
* xfs: sanitize qh_lock wrappersChristoph Hellwig2009-02-091-1/+0
| | | | | | | | | | Get rid of various obsfucating wrappers for accessing the quota hash lock, we only keep the accessors for accessing the mplist and freelist locks as they encode a multi-level datastructure walk. But make sure all of them are defined in the same way as simple macros. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <david@fromorbit.com>

* no explicit xfs_iflush for special inodes during unmountChristoph Hellwig2008-12-041-1/+1
| | | | | | | | | | | Currently we explicitly call xfs_iflush on the quota, real-time and root inodes from xfs_unmount_flush. But we just called xfs_sync_inodes with SYNC_ATTR and do an XFS_bflush aka xfs_flush_buftarg to make sure all inodes are on disk already, so there is no need for these special cases.

* [XFS] Clean up dquot pincount code.Peter Leckie2008-10-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | This is a code cleanup and optimization that removes a per mount point spinlock from the quota code and cleans up the code. The patch changes the pincount from being an int protected by a spinlock to an atomic_t allowing the pincount to be manipulated without holding the spinlock. This cleanup also protects against random wakup's of both the aild and xfssyncd by reevaluating the pincount after been woken. Two latter patches will address the Spurious wakeups.

* [XFS] Clean up quotamount error handling.David Chinner2008-04-181-1/+1
| | | | | | | | | | | | | | 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.

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!
