-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:

- mm/vmstat.c: uninline node_page_state()
+ scsi: aacraid: send AIF request post IOP RESET
- With x86_64 (config http://ozlabs.org/~akpm/config-akpm2.txt) and old gcc
- (4.4.4), drivers/base/node.c:node_read_meminfo() is using 2344 bytes of
- stack. Uninlining node_page_state() reduces this to 440 bytes.
+ After IOP reset completion, AIF request command is not issued to the
+ controller. Driver schedules a worker thread to issue a AIF request command
+ after IOP reset completion.
- The stack consumption issue is fixed by newer gcc (4.8.4) however with
- that compiler this patch reduces the node.o text size from 7314 bytes to
- 4578.

- mm, page_alloc: use masks and shifts when converting GFP flags to migrate types
+commit 572ee53a9badf62f3973d66f6475f9ce69720a25
+Author: Balsundar P <balsundar.p@microsemi.com>
+Date: Tue Oct 15 11:52:02 2019 +0530
+
+ scsi: aacraid: check adapter health
+
+ Currently driver waits for the command IOCTL from the firmware and if the
+ firmware enters nonresponsive state, the driver doesn't respond till the
+ firmware is responsive again.
- This patch redefines which GFP bits are used for specifying mobility and
- the order of the migrate types. Once redefined it's possible to convert
- GFP flags to a migrate type with a simple mask and shift. The only
- downside is that readers of OOM kill messages and allocation failures may
- have been used to the existing values but scripts/gfp-translate will help.
+ Check that firmware is alive, otherwise return -EBUSY.

- mm, page_alloc: remove MIGRATE_RESERVE
+commit e2fd90dd2ed87bdcfdfb640f06da48fd23efa080
+Author: Balsundar P <balsundar.p@microsemi.com>
+Date: Tue Oct 15 11:52:01 2019 +0530
+
+ scsi: aacraid: setting different timeout for src and thor
- MIGRATE_RESERVE preserves an old property of the buddy allocator that
- existed prior to fragmentation avoidance -- min_free_kbytes worth of pages
- tended to remain contiguous until the only alternative was to fail the
- allocation. At the time it was discovered that high-order atomic
- allocations relied on this property so MIGRATE_RESERVE was introduced. A
- later patch will introduce an alternative MIGRATE_HIGHATOMIC so this patch
- deletes MIGRATE_RESERVE and supporting code so it'll be easier to review.
- Note that this patch in isolation may look like a false regression if
- someone was bisecting high-order atomic allocation failures.
+ Set 180 second timeout for thor and 60 seconds for src controllers.
