+Subject: xfs: give all workqueues rescuer threads
+
+We're consistently hitting deadlocks here with XFS on recent kernels.
+After some digging through the crash files, it looks like everyone in
+the system is waiting for XFS to reclaim memory.
+
+Something like this:
+

+
+xfs_log_force_lsn is waiting for logs to get cleaned, which is waiting
+for IO, which is waiting for workers to complete the IO which is waiting
+for worker threads that don't exist yet:
+
+PID: 2752451 TASK: ffff880bd6bdda00 CPU: 37 COMMAND: "kworker/37:1"

+
+I think we should be using WQ_MEM_RECLAIM to make sure this thread
+pool makes progress when we're not able to allocate new workers.
