H A D | fs-writeback.c | f0d07b7f Thu May 03 07:47:59 CDT 2012 Jan Kara <jack@suse.cz> writeback: Remove wb->list_lock from writeback_single_inode()
writeback_single_inode() doesn't need wb->list_lock for anything on entry now. So remove the requirement. This makes locking of writeback_single_inode() temporarily awkward (entering with i_lock, returning with i_lock and wb->list_lock) but it will be sanitized in the next patch.
Also inode_wait_for_writeback() doesn't need wb->list_lock for anything. It was just taking it to make usage convenient for callers but with writeback_single_inode() changing it's not very convenient anymore. So remove the lock from that function.
