Btrfs: pass lockdep rwsem metadata to async commit transaction The freeze rwsem is taken by sb_start_intwrite() and dropped during the commit_ or end_transaction(). In the async case, that happens in a worker thread. Tell lockdep the calling thread is releasing ownership of the rwsem and the async thread is picking it up. XFS plays the same trick in fs/xfs/xfs_aops.c. Signed-off-by: Sage Weil <sage@inktank.com>
