Hello Christoph,
Sorry that I have not yet had the time to review these patches. But I
cloned git://git.infradead.org/users/hch/block.git, checked out the
block-pc-refactor branch, merged it with v4.10-rc5 and installed it on
a development server. Unfortunately a kernel oops occurred during boot
(see also the attached screenshot). gdb translates the crash address
into the following:
$ gdb vmlinux
(gdb) list *('__scsi_execute.isra.19'+0x13c)
0xffffffff814a690c is in __scsi_execute (drivers/scsi/scsi_lib.c:260).
255 memset(buffer + (bufflen - rq->resid_len), 0, rq->resid_len);
256
257 if (resid)
258 *resid = rq->resid_len;
259 if (rq->sense_len)
260 memcpy(sense, rq->sense, SCSI_SENSE_BUFFERSIZE);
261 ret = req->errors;
262 out:
263 blk_put_request(req);
264
