[PATCH 3.10 03/21] block: provide compat ioctl for BLKZEROOUT

From: Greg Kroah-Hartman
Date: Tue Jul 29 2014 - 22:12:14 EST


3.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Mikulas Patocka <mpatocka@xxxxxxxxxx>

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.
