Subject: [PATCH 02/20] nvme: fix initialization of the zone bitmaps
Date: Mon, 28 Sep 2020 14:34:44 +0200 [thread overview]
Message-ID: <20200928123502.435373-3-hch@lst.de> (raw)
In-Reply-To: <20200928123502.435373-1-hch@lst.de>
The removal of the ->revalidate_disk method broke the initialization of
the zone bitmaps, as nvme_revalidate_disk now never gets called during
initialization.
Move the zone related code from nvme_revalidate_disk into a new helper in
zns.c, and call it from nvme_alloc_ns in addition to nvme_validate_ns to
ensure the zone bitmaps are initialized during probe.
