| |
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
