    Merge tag 'erofs-for-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

    Pull erofs updates from Gao Xiang:
     "The most notable change is to support superblock sharing for
      composefs, thanks to Giuseppe again.

      Another one switches to iomap for file-backed mounts on unencoded
      inodes, which enables efficient sub-folio I/Os. The others are all
      random ones.

      Summary:
       - Support superblock sharing for file-backed mounts
       - Use iomap for file-backed mounts on unencoded inodes
       - Minor fixes and cleanups"
