Merge tag 'for-5.14-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fix from David Sterba: "One more fix that I think qualifies for a late merge. It's a revert of a one-liner fix that meanwhile got backported to stable kernels and we got reports from users. The broken fix prevents creating compressed inline extents, which could be noticeable on space consumption. Technically it's a regression as the patch was merged in 5.14-rc1 but got propagated to several stable kernels and has higher exposure than a 'typical' development cycle bug" * tag 'for-5.14-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: Revert "btrfs: compression: don't try to compress if we don't have enough pages"
