Hi Linus,

Could you consider this pull request for 6.6-rc1?

In this cycle, xattr bloom filter feature is introduced to speed up
negative xattr lookups, which was originally suggested by Alexander
for Composefs use cases.

Besides, DEFLATE algorithm is now supported, which can be used together
with hardware accelerators for our cloud workloads.  Each supported
compression algorithm can be selected on a per-file basis for specific
access patterns too.

There are some random fix and cleanups as usual.  All commits have been
in -next for a while and no potential merge conflict is observed.

Thanks,
Gao Xiang
