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. Cc: <stable@vger.kernel.org> # v4.4+ Fixes: bbd3e064362e ("block: add an API for Persistent Reservations") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Fold in followup patch from Arnd with missing pr.h header include. Signed-off-by: Jens Axboe <axboe@kernel.dk>
