To close sget() races we'll need to be able to set cifs_sb up before we get the superblock, so we'll want to be able to do cifs_mount() earlier. Fortunately, it's easy to do - setting ->s_maxbytes can be done in cifs_read_super(), ditto for ->s_time_gran and as for putting MS_POSIXACL into ->s_flags, we can mirror it in ->mnt_cifs_flags until cifs_read_super() is called. Kill unused 'devname' argument, while we are at it... Acked-by: Pavel Shilovsky <piastryyy@gmail.com> Reviewed-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
