Amir Goldstein 795bb82d12 fsnotify: fix UAF from FS_ERROR event on a shutting down filesystem ... Protect against use after free when filesystem calls fsnotify_sb_error() during fs shutdown. Move freeing of sb->s_fsnotify_info to destroy_super_work(), because it may be accessed from fs shutdown context.
