Subject: [PATCH 06/24] compat_ioctl: block: handle Persistent Reservations
Date: Wed, 11 Dec 2019 21:42:40 +0100
Message-ID: <20191211204306.1207817-7-arnd@arndb.de> (raw)
In-Reply-To: <20191211204306.1207817-1-arnd@arndb.de>

These were added to blkdev_ioctl() in linux-5.5 but not
blkdev_compat_ioctl, so add them now.

Cc: <stable@vger.kernel.org> # v4.4+
Fixes: bbd3e064362e ("block: add an API for Persistent Reservations")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
