Subject: [PATCH AUTOSEL 5.8 12/29] nvme-pci: disable the write zeros command for Intel 600P/P3100
Date: Mon, 28 Sep 2020 21:30:09 -0400	[thread overview]
Message-ID: <20200929013027.2406344-12-sashal@kernel.org> (raw)
In-Reply-To: <20200929013027.2406344-1-sashal@kernel.org>

From: David Milburn <dmilburn@redhat.com>

[ Upstream commit ce4cc3133dc72c31bd49ddcf22d0f9eeff47a761 ]

The write zeros command does not work with 4k range.

bash-4.4# ./blkdiscard /dev/nvme0n1p2
bash-4.4# strace -efallocate xfs_io -c "fzero 536895488 2048" /dev/nvme0n1p2
fallocate(3, FALLOC_FL_ZERO_RANGE, 536895488, 2048) = 0
+++ exited with 0 +++
bash-4.4# dd bs=1 if=/dev/nvme0n1p2 skip=536895488 count=512 | hexdump -C
