Hi,
btrfs-progs 3.19.1 have been released. Mostly a bugfix release with an
enhancement to convert.
User visible changes:
- convert:
- new option to specify metadata block size
- --no-progress actually works
- restore: properly handle the page boundary corner case
- build fixes:
- missing

This test tests three conditions where orphan items need to be cleaned up:
1) Default subvolume is fs tree root (mkfs default)
2) Default subvolume has been set explicitly to another subvolume (set-default)
3) Looking up a subvolume during a traversal
In the kernel, these three cases use separate
Due to insufficient check in btrfs_is_valid_xattr, this unexpectedly
works:
$ touch file
$ setfattr -n user. -v 1 file
$ getfattr -d file
user.=1
ie. the missing attribute name after the namespace.

Although btrfs-convert can rollback converted btrfs, it still has some
limitation to ensure rollback.
Add a warning on the limitations.
Also add a note for users who decides to go on with btrfs and don't need
the rollback ability.
