Subject: [PATCH 3.13 160/259] block: provide compat ioctl for BLKZEROOUT -stable review patch.  If anyone has any objections, please let me know.


From: Mikulas Patocka <>

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.
