Pull erofs updates from Gao Xiang:
 "In this cycle, we continue converting to use meta buffers for all
  remaining uncompressed paths to prepare for the upcoming subpage,
  folio and fscache features.

  We also fixed a double-free issue when sysfs initialization fails,
  which was reported by syzbot.

  Besides, in order for the userspace to control per-file timestamp
  easier, we now switch to record mtime instead of ctime with a
  compatible feature marked. And there are also some code cleanups and
  documentation update as usual.

  Summary:

   - Avoid using page structure directly for all uncompressed paths

   - Fix a double-free issue when sysfs initialization fails

   - Complete DAX description for erofs

   - Use mtime instead since there's no (easy) way for users to control
     ctime

   - Several code cleanups"
