Merge tag 'erofs-for-6.16-rc1' of git://git./linux/kernel/git/xiang/erofs

Pull erofs updates from Gao Xiang:
 "In this cycle, Intel QAT hardware accelerators are supported to
  improve DEFLATE decompression performance. I've tested it with the
  enwik9 dataset of 1 MiB pclusters on our Intel Sapphire Rapids
  bare-metal server and a PL0 ESSD, and the sequential read performance
  even surpasses LZ4 software decompression on this setup.

  In addition, a `fsoffset` mount option is introduced for file-backed
  mounts to specify the filesystem offset in order to adapt customized
  container formats.

  And other improvements and minor cleanups. Summary:

   - Add a `fsoffset` mount option to specify the filesystem offset

   - Support Intel QAT accelerators to boost up the DEFLATE algorithm

   - Initialize per-CPU workers and CPU hotplug hooks lazily to avoid
     unnecessary overhead when EROFS is not mounted

   - Fix file handle encoding for 64-bit NIDs

   - Minor cleanups"
