From 3b3a1814d1703027f9867d0f5cbbfaf6c7482474 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Wed, 2 Jul 2014 12:46:23 -0400 Subject: [PATCH] block: provide compat ioctl for BLKZEROOUT 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. Signed-off-by: Mikulas Patocka Cc: stable@vger.kernel.org # 3.7+ Acked-by: Martin K.
