dm ioctl: do not leak argv if target message only contains whitespace If 'argc' is zero we jump to the 'out:' label, but this leaks the (unused) memory that 'dm_split_args()' allocated for 'argv' if the string being split consisted entirely of whitespace. Jump to the 'out_argv:' label instead to free up that memory. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Cc: stable@kernel.org Signed-off-by: Alasdair G Kergon <agk@redhat.com>
