Btrfs devel - Apr 2011 - files on not mounted subvolumes - mysql complains read only

When I''ve used btrfs subvolume, without separately mouting it, for
mysql database dir I''ve got
Fatal error: Can''t open and lock privilege tables: Table
''host'' is read only
when starting mysql. When I''ve put mysql database dir in root of
btrfs, not a subvolume, mysql works fine.
I''ve checked file for host table, but I could write to it no problem
(on subvolume without mouting). I dont know what could be the problem.
I did not check it when mouting a subvolume separately

This has been fixed. You can pull the for-linus branch of the btrfs-unstable
tree, or Linus'' linux-2.6, or wait for v2.6.39-rc2 to be announced.
