+Subject: [PATCH] io_uring: don't block level reissue off completion path
+
+Some setups, like SCSI, can throw spurious -EAGAIN off the softirq
+completion path. Normally we expect this to happen inline as part
+of submission, but apparently SCSI has a weird corner case where it
+can happen as part of normal completions.
+
+This should be solved by having the -EAGAIN bubble back up the stack
+as part of submission, but previous attempts at this failed and we're
+not just quite there yet. Instead we currently use REQ_F_REISSUE to
+handle this case.
+
+For now, catch it in io_rw_should_reissue() and prevent a reissue
+from a bogus path.

-
-The BUG code told that extent tree wants to grow but no metadata was
-reserved ahead of time.  From my investigation into this issue, the root
-cause it that although enough metadata is not reserved, there should be
-enough for following use.  Rightmost extent is merged into its left one
-due to a certain times of marking extent written.  Because during
-marking extent written, we got many physically continuous extents.  At
-last, an empty extent showed up and the rightmost path is removed from
-extent tree.
-
-Add a new mechanism to reuse extent block cached in dealloc which were
-just unlinked from extent tree to solve this crash issue.
-
-Criteria is that during marking extents *written*, if extent rotation
-and merging results in unlinking extent with growing extent tree later
-without any metadata reserved ahead of time, try to reuse those extents
-in dealloc in which deleted extents are cached.
-
-Also, this patch addresses the issue John reported that ::dw_zero_count
-is not calculated properly.
-
-After applying this patch, the issue John reported was gone.  Thanks for
-the reproducer provided by John.  And this patch has passed
-ocfs2-test(29 cases) suite running by New H3C Group.

+However, the root bus has two contiguous apertures that can contain the

+
+Coalesce contiguous apertures so we can allocate from the entire contiguous
+region.

+This is the second take of commit 65db04053efe ("PCI: Coalesce host

+by address, but that makes NVMe stop working on QEMU ppc:sam460ex:

+Since the apertures on HP EliteDesk 805 G6 are already in ascending

+Remove the sorting part to avoid the regression on ppc:sam460ex.

-
-Some guests OSes (including Windows 10) write to MSR 0xc001102c
-on some cases (possibly while trying to apply a CPU errata).
-Make KVM ignore reads and writes to that MSR, so the guest won't
-crash.
-
-The MSR is documented as "Execution Unit Configuration (EX_CFG)",
-at AMD's "BIOS and Kernel Developer's Guide (BKDG) for AMD Family
-15h Models 00h-0Fh Processors".

+Subject: [PATCH] ocfs2: mount fails with buffer overflow in strlen
+
+Starting with kernel 5.11 built with CONFIG_FORTIFY_SOURCE mouting an
+ocfs2 filesystem with either o2cb or pcmk cluster stack fails with the
+trace below. Problem seems to be that strings for cluster stack and
+cluster name are not guaranteed to be null terminated in the disk
+representation, while strlcpy assumes that the source string is always
+null terminated. This causes a read outside of the source string
+triggering the buffer overflow detection.
+
+detected buffer overflow in strlen
