The patch below does not apply to the 5.4-stable tree.
If someone wants it applied there, or to any other stable or longterm
tree, then please email the backport, including the original git commit
id to [off-list ref].

The code in versions from 5.4 to 4.4 is the same and the merge conflict
can be resolved from that (eg. from file
stable.git/releases/./5.4.136/btrfs-compression-don-t-try-to-compress-if-we-don-t-have-enough-pages.patch)
