-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.

-
-this modifies the upstream kernel build to call an Ubuntu script which
-we remove before building. it would also be required by any module
-builds afterwards and is not shipped by Ubuntu's kernel packages either.

-Subject: [PATCH] kvm: x86: Add AMD's EX_CFG to the list of ignored MSRs
-
-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".
