Pull erofs updates from Gao Xiang:
"The LZ4 global buffer count is now configurable instead of the
previous per-CPU buffers, which is useful for bare metals with
hundreds of CPUs. A reserved buffer pool for LZ4 decompression can
also be enabled to minimize the tail allocation latencies under the
low memory scenarios with heavy memory pressure.
In addition, Zstandard algorithm is now supported as an alternative
since it has been requested by users for a while.
There are some random cleanups as usual.
Summary:
- Make LZ4 global buffers configurable instead of per-CPU buffers
- Add a reserved buffer pool for LZ4 decompression for lower latencies
- Support Zstandard compression algorithm as an alternative
- Derive fsid from on-disk UUID for .statfs() if possible
- Minor cleanups"
