From: Mikulas Patocka <mpatocka@redhat.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 3b3a1814d1703027f9867d0f5cbbfaf6c7482474 upstream.
This patch provides the compat BLKZEROOUT ioctl. The argument is a pointer to two uint64_t values, so there is no need to translate it.
