From: Eric Sandeen <[email protected]> gfs2_ail_empty_gl() contains an "inline version" of gfs2_trans_begin(), so it needs an explicit sb_start_intwrite() as well, to balance the sb_end_intwrite() which will be called by gfs2_trans_end().
With this, xfstest 068 passes on lock_nolock local gfs2. Without it, we reach a writer count of -1 and get stuck.
