Subject: remove the cmd_type field from struct request
Date: Tue, 31 Jan 2017 16:57:21 +0100 [thread overview]
Message-ID: <1485878251-6107-1-git-send-email-hch@lst.de> (raw)
Hi Jens,
this series gets rid of the cmd_type field in struct request and
instead folds it into the REQ_OP* space. This reduces the size of
struct request, and leads to a single op namespace that drivers
can easily switch on. Except for the legacy ide driver which has
a mess of different request types [1] this also nicely cleans up the
code.
Note that the patches are on top of the
"make SCSI passthrough support optional"
series I sent out on Saturday. To make life easier I also have a git
tree available here:
git://git.infradead.org/users/hch/block.git cmd_type
http://git.infradead.org/users/hch/block.git/shortlog/refs/heads/cmd_type
[1] which were a pain in the ass to untangle and debug during development,
it's really time for it to die..
