Merge tag 'for-5.11-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fix from David Sterba:
"A regression fix caused by a refactoring in 5.11.
A corrupted superblock wouldn't be detected by checksum verification
due to wrongly placed initialization of the checksum length, thus
making memcmp always work"
* tag 'for-5.11-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: initialize fs_info::csum_size earlier in open_ctree
