[GIT PULL] erofs updates for 6.2-rc1 (fscache part inclusive)

[Gao Xiang]

Hi Linus,

Once the merge window opens, could you consider this pull request for
6.2-rc1?

In this cycle, large folios are now enabled in the iomap/fscache mode
for uncompressed files first.  In order to do that, we've also cleaned
up better interfaces between erofs and fscache, which are acked by
fscache/netfs folks and included in this pull request.

Other than that, there are random fixes around erofs over fscache and
crafted images by syzbot, minor cleanups and documentation updates.

Note that there could be a trivial conflict between erofs and vfs
tree according to linux-next report [1].

Happy Holidays!
Gao Xiang
