Merge tag 'erofs-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs
Pull erofs updates from Gao Xiang: "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. Summary: - Enable large folios for iomap/fscache mode - Avoid sysfs warning due to mounting twice with the same fsid and domain_id in fscache mode - Refine fscache interface among erofs, fscache, and cachefiles - Use kmap_local_page() only for metabuf - Fixes around crafted images found by syzbot - Minor cleanups and documentation updates" * tag 'erofs-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs: erofs: validate the extent length for uncompressed pclusters erofs: fix missing unmap if z_erofs_get_extent_compressedlen() fails erofs: Fix pcluster memleak when its block address is zero erofs: use kmap_local_page() only for erofs_bread() erofs: enable large folios for fscache mode erofs: support large folios for fscache mode erofs: switch to prepare_ondemand_read() in fscache mode fscache,cachefiles: add prepare_ondemand_read() callback erofs: clean up cached I/O strategies erofs: update documentation erofs: check the uniqueness of fsid in shared domain in advance erofs: enable large folios for iomap mode
