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"

erofs: use meta buffers for inode lookup

This converts the remaining inode lookup part by using metabuf in a
straight-forward way. Except that it doesn't use kmap_atomic()
anymore since we now have to maintain two metabufs together.

After this patch, all uncompressed paths are handled with metabuf
instead of page structure.

Merge tag 'erofs-for-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

Pull erofs updates from Gao Xiang:
"In this cycle, direct I/O and fsdax support for uncompressed files are
now added in order to avoid double-caching for loop device and VM
container use cases. All uncompressed cases are now turned into iomap
infrastructure, which looks much simpler and cleaner.

In addition, fiemap support is added for both (un)compressed files by
using iomap infrastructure as well so end users can easily get file
distribution. We've also added chunk-based uncompressed files support
for data deduplication as the next step of VM container use cases.

Summary:

- support direct I/O for all uncompressed files

- support fsdax for non-tailpacking regular files

- use iomap infrastructure for all uncompressed cases

- support fiemap for both (un)compressed files

- introduce chunk-based files for chunk deduplication

- some cleanups"

erofs: introduce chunk-based file on-disk format
erofs: add fiemap support with iomap
erofs: add support for the full decompressed length
erofs: remove the mapping parameter from erofs_try_to_free_cached_page()
