Merge tag 'erofs-for-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

Pull erofs updates from Gao Xiang:
 "The most notable change is the removal of the fscache backend: it has
  been deprecated for almost two years, mainly because EROFS file-backed
  mounts and fanotify pre-content hooks (together with erofs-utils) now
  provide better functionality and simpler codebase. In addition,
  fscache has depended on netfslib for years, which is undesirable for
  EROFS since it is a local filesystem. More details in [1].

  In addition, sparse support has been added to the pcluster layout,
  which is helpful for large sparse AI datasets, and map requests for
  chunk-based inodes have been optimized to be more efficient as well.
  There are also the usual fixes and cleanups.

  Summary:

   - Report more consecutive chunks of the same type for
     each iomap request

   - Add sparse support for the pcluster layout

   - Update the EROFS documentation overview

   - Remove the deprecated fscache backend

   - Various fixes and cleanups"
