BTRFS: support NFSv2 export

2015-10-06T13:55:23+00:00

The "fh_len" passed to ->fh_to_* is not guaranteed to be that same as
that returned by encode_fh - it may be larger.

With NFSv2, the filehandle is fixed length, so it may appear longer
than expected and be zero-padded.

So we must test that fh_len is at least some value, not exactly equal
to it.

VFS: normal filesystems (and lustre): d_inode() annotations

2015-04-15T19:06:57+00:00

that's the bulk of filesystem drivers dealing with inodes of their own

btrfs: kill the key type accessor helpers

2014-09-17T20:37:12+00:00

btrfs_set_key_type and btrfs_key_type are used inconsistently along with
open coded variants. Other members of btrfs_key are accessed directly
without any helpers anyway.

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.

Btrfs: cleanup: don't check the same thing twice

2013-06-14T15:29:30+00:00

btrfs_read_fs_root_no_name() already checks if btrfs_root_refs()
is zero and returns ENOENT in this case. There is no need to do
it again in six places.

->encode_fh() API change

2012-05-30T03:28:33+00:00

pass inode + parent's inode or NULL instead of dentry + bool saying
whether we want the parent or not.

NOTE: that needs ceph fix folded in.

btrfs: replace many BUG_ONs with proper error handling

2012-03-22T10:52:54+00:00

 btrfs currently handles most errors with BUG_ON. This patch is a work-in-
 progress but aims to handle most errors other than internal logic
 errors and ENOMEM more gracefully.

 This iteration prevents most crashes but can run into lockups with
 the page lock on occasion when the timing "works out."

btrfs: let ->s_fs_info point to fs_info, not root...

2012-01-09T00:35:37+00:00

the latter can be obtained from the former (by looking as ->tree_root)
just as cheaply as we currently are doing the other way round.
