Subject: [PATCH] raw: deprecate the raw driver
Date: Wed, 19 Aug 2020 09:35:33 +0200 [thread overview]
Message-ID: <20200819073533.1808361-1-hch@lst.de> (raw)
The raw driver has been replaced by O_DIRECT support on the block device
in 2002. Deprecate it to prepare for removal in a few kernel releases.
Signed-off-by: Christoph Hellwig <hch@lst.de>

Jens, I wonder if we can sneak this into 5.9 to have a longer deprecation
period?
