Al Viro 378ff1a53b fix deadlock in cifs_ioctl_clone() ... It really needs to check that src is non-directory *and* use {un,}lock_two_nodirectories(). As it is, it's trivial to cause double-lock (ioctl(fd, CIFS_IOC_COPYCHUNK_FILE, fd)) and if the last argument is an fd of directory, we are asking for trouble by violating the locking order - all directories go before all non-directories. If the last argument is an fd of parent directory, it has 50% odds of locking child before parent, which will cause AB-BA deadlock if we race with unlink().
