GCC 4.6 now warnings about variables set but not used. Fix the trivially fixable warnings of this sort. Signed-off-by: Christoph Hellwig Signed-off-by: Alex Elder

xfs: Extend project quotas to support 32bit project ids

2010-10-18T20:08:08Z

This patch adds support for 32bit project quota identifiers. On disk format is backward compatible with 16bit projid numbers. projid on disk is now kept in two 16bit values - di_projid_lo (which holds the same position as old 16bit projid value) and new di_projid_hi (takes existing padding) and converts from/to 32bit value on the fly. xfs_admin (for existing fs), mkfs.xfs (for new fs) needs to be used to enable PROJID32BIT support.

xfs: remove xfs_iput

2010-07-26T18:16:44Z

xfs_iput is just a small wrapper for xfs_iunlock + IRELE. Having this out of line wrapper means the trace events in those two can't track their caller properly. So just remove the wrapper and opencode the unlock + rele in the few callers. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Chinner

xfs: drop dmapi hooks

2010-07-26T18:16:33Z

Dmapi support was never merged upstream, but we still have a lot of hooks bloating XFS for it, all over the fast pathes of the filesystem. This patch drops over 700 lines of dmapi overhead. If we'll ever get HSM support in mainline at least the namespace events can be done much saner in the VFS instead of the individual filesystem, so it's not like this is much help for future work.

xfs: remove block number from inode lookup code

2010-06-24T01:35:17Z

The block number comes from bulkstat based inode lookups to shortcut the mapping calculations. We ar enot able to trust anything from bulkstat, so drop the block number as well so that the correct lookups and mappings are always done. Signed-off-by: Dave Chinner Reviewed-by: Christoph Hellwig

xfs: rename XFS_IGET_BULKSTAT to XFS_IGET_UNTRUSTED

2010-06-24T01:15:47Z

Inode numbers may come from somewhere external to the filesystem (e.g. file handles, bulkstat information) and so are inherently untrusted. Rename the flag we use for these lookups to make it obvious we are doing a lookup of an untrusted inode number and need to verify it completely before trying to read it from disk.

xfs: always use iget in bulkstat

2010-06-23T08:11:11Z

The non-coherent bulkstat versionsthat look directly at the inode buffers causes various problems with performance optimizations that make increased use of just logging inodes. This patch makes bulkstat always use iget, which should be fast enough for normal use with the radix-tree based inode cache introduced a while ago.

xfs: return inode fork offset in bulkstat for fsr

2010-03-05T17:02:07Z

So that fsr can attempt to get the fork offset of the temporary inode it uses the same as the inode it is defragmenting, pass the fork offset out in the bulkstat information. The bulkstat structure has padding that has always been zeroed, so userspace can tell if this field is set or not by use of the xattr present flag and a non-zero value for the fork offset.

xfs: replace KM_LARGE with explicit vmalloc use

2010-01-21T19:44:56Z

We use the KM_LARGE flag to make kmem_alloc and friends use vmalloc if necessary. As we only need this for a few boot/mount time allocations just switch to explicit vmalloc calls there. Signed-off-by: Christoph Hellwig Signed-off-by: Alex Elder
