-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:
-
-PID: 2733434 TASK: ffff8808cd242800 CPU: 19 COMMAND: "java"

-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:

-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.
