Subject: [GIT PULL] erofs updates for 7.0-rc1
Hi Linus,
Could you consider this pull request for 7.0-rc1?
In this cycle, inode page cache sharing among filesystems on the same
machine is now supported, which is particularly useful for high-density
hosts running tens of thousands of containers.
In addition, we fully isolate the EROFS core on-disk format from other
optional encoded layouts since the core on-disk part is designed to be
simple, effective, and secure. Users can use the core format to build
unique golden immutable images and import their filesystem trees
directly from raw block devices via DMA, page-mapped DAX devices, and/or
file-backed mounts without having to worry about unnecessary intrinsic
consistency issues found in other generic filesystems by design.
However, the full vision is still working in progress and will spend
more time to achieve final goals.
There are other improvements and bug fixes as usual, as listed below.
All commits have been in -next for a while. Note that I have merged the
`vfs-7.0.iomap` branch in order to import iomap changes and route the
iomap updates properly, so the same merge conflicts are observed as in:
https://lore.kernel.org/r/20260206-vfs-iomap-v70-71e0b356ce5c@brauner
Thanks,
Gao Xiang

erofs: fix UAF issue for file-backed mounts w/ directio option (2026-02-06 15:30:35 +0800)
----------------------------------------------------------------
Changes since last update:
- Support inode page cache sharing among filesystems
- Formally separate optional encoded (aka compressed) inode layouts
(and the implementations) from the EROFS core on-disk aligned plain
format for future zero-trust security usage
- Improve performance by caching the fact that an inode does not have
a POSIX ACL
- Improve LZ4 decompression error reporting
- Enable LZMA by default and promote DEFLATE and Zstandard algorithms
out of EXPERIMENTAL status
- Switch to inode_set_cached_link() to cache symlink lengths
- random bugfixes and minor cleanups
