staging: erofs: introduce erofs shrinker This patch adds a dedicated shrinker targeting to free unneeded memory consumed by a number of erofs in-memory data structures. Like F2FS and UBIFS, it also adds: - sbi->umount_mutex to avoid races on shrinker and put_super - sbi->shrinker_run_no to not revisit recently scaned objects Signed-off-by: Gao Xiang <gaoxiang25@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
