Subject: [PATCH 1/3] btrfs: Initialize btrfs_io_ctl instead of memsetting it
Date: Mon, 25 Feb 2019 13:07:42 -0600	[thread overview]
Message-ID: <20190225190744.21664-1-rgoldwyn@suse.de> (raw)

From: Goldwyn Rodrigues <rgoldwyn@suse.com>

io_ctl_init() memsets it to zero anyways. However, I presume the
memset was added to avoid the WARN_ON in io_ctl_init().
