Bob Peterson d11e5b96ef gfs2: fix scheduling while atomic bug in glocks ... commit 20265d9a67e40eafd39a8884658ca2e36f05985d upstream. Before this patch, in the unlikely event that gfs2_glock_dq encountered a withdraw, it would do a wait_on_bit to wait for its journal to be recovered, but it never released the glock's spin_lock, which caused a scheduling-while-atomic error. This patch unlocks the lockref spin_lock before waiting for recovery.
