Subject: use block_device based APIs in block layer consumers
Date: Wed, 6 Apr 2022 08:04:49 +0200 [thread overview]
Message-ID: <20220406060516.409838-1-hch@lst.de> (raw)
Hi Jens,
this series cleanups up the block layer API so that APIs consumed
by file systems are (almost) only struct block_devic based, so that
file systems don't have to poke into block layer internals like the
request_queue.
I also found a bunch of existing bugs related to partition offsets
and discard so these are fixed while going along.
