block: drop device references in bsg_queue_rq()

2019-09-23T17:17:24+00:00

Make sure that bsg_queue_rq() calls put_device() if an error is
encountered after get_device() was successful.

block: switch all files cleared marked as GPLv2 or later to SPDX tags

2019-04-30T22:11:59+00:00

All these files have some form of the usual GPLv2 or later boilerplate.
Switch them to use SPDX tags instead.

scsi: bsg-lib: handle bidi requests without block layer help

2019-02-06T02:27:40+00:00

We can just stash away the second request in struct bsg_job instead of
using the block layer req->next_rq field, allowing for the eventual removal
of the latter.

bsg: move bsg-lib parts outside of request queue

2018-11-07T20:42:33+00:00

Get rid of the special bsg job fn and timeout handler, move them
into a private bsg_set instead.

Mostly from Christoph, with fixes for error handling and cleanups.

block: kill legacy parts of timeout handling

2018-11-07T20:42:33+00:00

The only user of legacy timing now is BSG, which is invoked
from the mq timeout handler. Kill the legacy code, and rename
the q->rq_timed_out_fn to q->bsg_job_timeout_fn.

bsg: pass in desired timeout handler

2018-11-07T20:42:32+00:00

This will ease in the conversion to blk-mq, where we can't set
a timeout handler after queue init.
