Subject: store a pointer to the block_device in struct bio (again)
Date: Tue, 1 Dec 2020 17:54:15 +0100 [thread overview]
Message-ID: <20201201165424.2030647-1-hch@lst.de> (raw)
Hi Jens,
this series switches back from storing the gendisk + partno to storing
a block_device pointer in struct bio. The reason is two fold: for one
the new struct block_device actually is always available, removing the
need to avoid originally. Second the merge struct block_device is much
more useful than the old one, as storing it avoids the need for looking
up what used to be hd_struct during partition remapping and I/O
accounting.
Note that this series depends on the posted but not merged
"block tracepoint cleanups" series.
