Dave Chinner 2ced19cbae xfs: make AIL tail pushing independent of the grant lock ... The xlog_grant_push_ail() currently takes the grant lock internally to sample the tail lsn, last sync lsn and the reserve grant head. Most of the callers already hold the grant lock but have to drop it before calling xlog_grant_push_ail(). This is a left over from when the AIL tail pushing was done in line and hence xlog_grant_push_ail had to drop the grant lock. AIL push is now done in another thread and hence we can safely hold the grant lock over the entire xlog_grant_push_ail call. Push the grant lock outside of xlog_grant_push_ail() to simplify the locking and synchronisation needed for tail pushing. This will reduce traffic on the grant lock by itself, but this is only one step in preparing for the complete removal of the grant lock. While there, clean up the formatting of xlog_grant_push_ail() to match the rest of the XFS code.
