From 075bc9872a9b364ca7391ae550b56907efabd07a Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 29 Nov 2019 11:28:22 +0100 Subject: compat_ioctl: block: handle Persistent Reservations commit b2c0fcd28772f99236d261509bcd242135677965 upstream. These were added to blkdev_ioctl() in linux-5.5 but not blkdev_compat_ioctl, so add them now.
