#     Merge tag 'for-5.1-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fix from David Sterba:
#      "One patch to fix a crash in io submission path, due to memory
#       allocation errors.
#     
#       In short, the multipage bio work that landed in 5.1 caused larger bios
#       that in turn require larger temporary memory for checksums. The patch
#       is a workaround, we're going to rework the allocation so it does not
#       require the vmalloc fallback.
#     
#       It took a while to identify that it's caused by patches in 5.1 and not
#       a patchset that did some changes in error handling in the code. I've
#       tested it on various memory/cpu combinations, it could hit OOM but
#       does not crash.
#     
#       The timestamp of the patch is less than a day due to updates in the
#       changelog, tests were running meanwhile"
