Subject: [PATCH v3 3/9] loop: Switch to set_capacity_revalidate_and_notify()
Date: Mon, 27 Apr 2020 09:42:16 +0200	[thread overview]
Message-ID: <20200427074222.65369-4-maco@android.com> (raw)
In-Reply-To: <20200427074222.65369-1-maco@android.com>

This was recently added to block/genhd.c, and takes care of both
updating the capacity and notifying userspace of the new size.
