gfs2: Don't sleep during glock hash walk In flush_delete_work, instead of flushing each individual pending delayed work item, cancel and re-queue them for immediate execution. The waiting isn't needed here because we're already waiting for all queued work items to complete in gfs2_flush_delete_work. This makes the code more efficient, but more importantly, it avoids sleeping during a rhashtable walk, inside rcu_read_lock(). Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
