| |
Hi Linus,
Could you consider this pull request for 6.4-rc1?
In this cycle, sub-page block support for uncompressed files is available. It's mainly used to enable golden 4k-block images on arm64 with 16/64k pages. In addition, end users could also use this feature to build a manifest to directly refer to golden tar data.
Besides, long xattr name prefix support is also introduced in this cycle to avoid too many xattrs with the same prefix (e.g. overlayfs xattrs). It's useful for erofs + overlayfs combination (like Composefs model): the image size is reduced by ~14% and runtime performance is also slightly improved.
Others are random fixes and cleanups as usual. All commits have been in -next for a while and currently there is only a minor merge conflict with the vfs-idmapping tree [1]. Christian also mentioned this in the related pull request.
Thanks, Gao Xiang

erofs: cleanup i_format-related stuffs (2023-04-17 01:15:55 +0800)
---------------------------------------------------------------- Changes since last update:
- Add sub-page block size support for uncompressed files;
- Support flattened block device for multi-blob images to be attached into virtual machines (including cloud servers) and bare metals;
- Support long xattr name prefixes to optimize images with common xattr namespaces (e.g. files with overlayfs xattrs) use cases;
- Various minor cleanups & fixes.
---------------------------------------------------------------- Gao Xiang (6): erofs: tidy up EROFS on-disk naming erofs: stop parsing non-compact HEAD index if clusterofs is invalid erofs: keep meta inode into erofs_buf erofs: get rid of z_erofs_fill_inode() erofs: sunset erofs_dbg() erofs: cleanup i_format-related stuffs
Jia Zhu (1): erofs: support flattened block device for multi-blob images
Jingbo Xu (12): erofs: avoid hardcoded blocksize for subpage block support erofs: set block size to the on-disk block size erofs: move several xattr helpers into xattr.c erofs: rename init_inode_xattrs with erofs_ prefix erofs: simplify erofs_xattr_generic_get() erofs: initialize packed inode after root inode is assigned erofs: move packed inode out of the compression part erofs: introduce on-disk format for long xattr name prefixes erofs: add helpers to load long xattr name prefixes erofs: handle long xattr name prefixes properly erofs: enable long extended attribute name prefixes erofs: fix potential overflow calculating xattr_isize
Yue Hu (1): erofs: don't warn ztailpacking feature anymore
