Package: src:linux Version: 7.2~rc2-1~exp1 Severity: wishlist Dear Debian kernel maintainers, Currently EROFS already ships CONFIG_EROFS_FS_PAGE_CACHE_SHARE in linux 7.0 as an optional feature. since it's already shipped and users can choose to use it at runtime or not, I hope this feature could be enabled in Debian. In short, I hope the debian kernels can enabled CONFIG_EROFS_FS_PAGE_CACHE_SHARE=y to match the latest erofs-utils 1.9.2. Thanks, Gao Xiang

From the EROFS policy perspective, almost every EROFS new feature will be marked as EXPERIMENTAL initially (e.g. EROFS LZMA, DEFLATE, ZSTD were all marked as EXPERIMENTAL): since experimental features are new, they could have some bugs so users need to know they are using a new feature (as the other new features, this feature also shows "EXPERIMENTAL EROFS page cache share support in use. Use at your own risk!" when mounting.) However, we always encourage users to enable, use and give feedback on them if possible (unless on some embedded systems), so that new features can drop experimental tag after a given period. On the functionality side, as the option describes, this feature enables inode sharing between filesystems, and it also needs to be explicitly enabled with a mount option "inode_share".
