btrfs: remove fs/btrfs/compat.h

2013-11-12T03:03:19+00:00

fs/btrfs/compat.h only contained trivial macro wrappers of drop_nlink() and inc_nlink(). This doesn't belong in mainline. Signed-off-by: Zach Brown Signed-off-by: Josef Bacik Signed-off-by: Chris Mason

Btrfs: Fix checkpatch.pl warnings

There were many, most are fixed now. struct-funcs.c generates some warnings but these are bogus. Signed-off-by: Chris Mason

Btrfs: compat code fixes

2008-11-20T15:22:27+00:00

The btrfs git kernel trees is used to build a standalone tree for compiling against older kernels. This commit makes the standalone tree work with 2.6.27 Signed-off-by: Chris Mason

Btrfs: Fixes for 2.6.28-rc API changes

* open/close_bdev_excl -> open/close_bdev_exclusive * blkdev_issue_discard takes a GFP mask now * Fix blkdev_issue_discard usage now that it is enabled Signed-off-by: Chris Mason

Remove Btrfs compat code for older kernels

2008-09-25T19:41:59+00:00

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

Btrfs: Add a write ahead tree log to optimize synchronous operations

2008-09-25T15:04:07+00:00

File syncs and directory syncs are optimized by copying their items into a special (copy-on-write) log tree. There is one log tree per subvolume and the btrfs super block points to a tree of log tree roots. After a crash, items are copied out of the log tree and back into the subvolume. See tree-log.c for all the details. Signed-off-by: Chris Mason

NFS support for btrfs - v3

2008-09-25T15:04:06+00:00

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 Signed-off-by: David Woodhouse Signed-off-by: Chris Mason

Btrfs: Add workaround for AppArmor changing remove_suid()

2008-09-25T15:04:02+00:00

In openSUSE 10.3, AppArmor modifies remove_suid to take a struct path rather than just a dentry. This patch tests that the kernel is openSUSE 10.3 or newer and adjusts the call accordingly. Debian/Ubuntu with AppArmor applied will also need a similar patch. Maintainers of btrfs under those distributions should build on this patch or, alternatively, alter their package descriptions to add -DREMOVE_SUID_PATH to the compiler command line.
