From: Jia Zhu <zhujia.zj@bytedance.com> anolis inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IB5UKT Reference: https://gitee.com/anolis/cloud-kernel/commit/d6c1b4c226b0 -------------------------------- ANBZ: #3211 commit 1015c1016c231b26d4e2c9b3da65b6c043eb97a3 upstream. Use kill_anon_super() instead of generic_shutdown_super() since the mount() in erofs fscache mode uses get_tree_nodev() and associated anon bdev needs to be freed.
