Subject: compat_ioctl: block: handle BLKREPORTZONE/BLKRESETZONE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=238d4e749b773eb58678ea93b8f6cfdf5c454b5a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

compat_ioctl: block: handle BLKREPORTZONE/BLKRESETZONE

commit 673bdf8ce0a387ef585c13b69a2676096c6edfe9 upstream.

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