#     Merge tag 'for-5.12-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fix from David Sterba:
#      "One more patch that we'd like to get to 5.12 before release.
#     
#       It's changing where and how the superblock is stored in the zoned
#       mode. It is an on-disk format change but so far there are no
#       implications for users as the proper mkfs support hasn't been merged
#       and is waiting for the kernel side to settle.
#     
#       Until now, the superblocks were derived from the zone index, but zone
#       size can differ per device. This is changed to be based on fixed
#       offset values, to make it independent of the device zone size.
#     
#       The work on that got a bit delayed, we discussed the exact locations
#       to support potential device sizes and usecases. (Partially delayed
#       also due to my vacation.) Having that in the same release where the
#       zoned mode is declared usable is highly desired, there are userspace
#       projects that need to be updated to recognize the feature. Pushing
#       that to the next release would make things harder to test"
