From: Gao Xiang Date: Fri, 30 Aug 2024 03:28:40 +0000 (+0800) Subject: erofs: mark experimental fscache backend deprecated X-Git-Tag: v6.12-rc1~206^2~7 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0d442ce0b3027e99491520a3a8585e8c4ffd79dc;p=thirdparty%2Fkernel%2Flinux.git erofs: mark experimental fscache backend deprecated Although fscache is still described as "General Filesystem Caching" for network filesystems and other things such as ISO9660 filesystems, it has actually become a part of netfslib recently, which was unexpected at the time when "EROFS over fscache" proposed (2021) since EROFS is entirely a disk filesystem and the dependency is redundant. Mark it deprecated and it will be removed after "fanotify pre-content hooks" lands, which will provide the same functionality for EROFS.
