Subject: bsg cleanup, part 2
Date: Thu, 29 Jul 2021 08:48:41 +0200 [thread overview]
Message-ID: <20210729064845.1044147-1-hch@lst.de> (raw)
Hi Martin,
this is the next round of bsg cleanups based on the previous scsi ioctl
changes. The biggest changes are major simplification of how the bsg
nodes are created and found, and a simplification of the interface
between the frontend in bsg.c and the two backends.
