* Btrfs: Fix checkpatch.pl warningsChris Mason2009-01-051-3/+5
| | | | | | | There were many, most are fixed now. struct-funcs.c generates some warnings but these are bogus. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Remove Btrfs compat code for older kernelsChris Mason2008-09-251-6/+0
| | | | | | | | Btrfs had compatibility code for kernels back to 2.6.18. These have been removed, and will be maintained in a separate backport git tree from now on. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: cleanup d_obtain_alias useageChristoph Hellwig2008-09-251-15/+2
| | | | | | | | | d_obtain_alias is intended as a tailcall that can pass in errors encoded in the inode pointer if needed, so use it that way instead of duplicating the error handling. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Btrfs: Fix NFS exporting of subvol roots.David Woodhouse2008-09-251-1/+12
| | | | | | | | | | | | | Date: Tue, 19 Aug 2008 22:20:17 +0100 btrfs_lookup_fs_root() only finds subvol roots which have already been seen and put into the cache. For btrfs_get_dentry() we actually have to go to the medium -- so use btrfs_read_fs_root_no_name() instead. In btrfs_get_parent(), notice when we've hit the root of the subvolume and return the real root instead.

* NFS support for btrfs - v3Balaji Rao2008-09-251-0/+208
Date: Mon, 21 Jul 2008 02:01:56 +0530 Here's an implementation of NFS support for btrfs. It relies on the fixes which are going in to 2.6.28 for the NFS readdir/lookup deadlock. This uses the btrfs_iget helper introduced previously. [dwmw2: Tidy up a little, switch to d_obtain_alias() w/compat routine, change fh_type, store parent's root object ID where needed, fix some get_parent() and fs_to_dentry() bugs] Signed-off-by: Balaji Rao <balajirrao@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
