USB: uas: Reduce can_queue to MAX_CMNDS

2016-03-18T16:19:02+00:00

The uas driver can never queue more then MAX_CMNDS (- 1) tags and tags
are shared between luns, so there is no need to claim that we can_queue
some random large number.

Not claiming that we can_queue 65536 commands, fixes the uas driver
failing to initialize while allocating the tag map with a "Page allocation
failure (order 7)" error on systems which have been running for a while
and thus have fragmented memory.

usb: storage: use usb_store_dbg instead of US_DEBUGPX

2016-02-21T04:21:53+00:00

The US_DEBUGPX macro uses printk without specifying a kernel log level, so
the default kernel log level is used, which may not match LOGLEVEL_DEBUG
used in usb_stor_dbg. Remove the macro and use usb_store_dbg instead.

usb: storage: ene_ub6250: Remove unnecessary cast in kfree

2016-02-03T21:48:12+00:00

Remove unnecassary casts in the argument to kfree.

Found using Coccinelle. The semantic patch used to find this is as follows:

//
@@
type T;
expression *f;
@@

- kfree((T *)(f));
+ kfree(f);

USB: uas: add full support for RESPONSE IU

2016-01-25T05:00:33+00:00

Some devices send response IUs when you'd expect a sense IU.
As a response to a wrong LUN that is within spec.
We cannot get away without handling for response IUs.
This version fixes the issues Hans raised.

uas: no gfp argument to uas_submit_urbs()

2015-12-01T22:29:21+00:00

This function must be called with a spinlock held.
Memory can be allocated only with GFP_ATOMIC. Passing
a gfp_t argument is a waste.

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2015-11-14T04:35:54+00:00

Pull final round of SCSI updates from James Bottomley:
 "Sorry for the delay in this patch which was mostly caused by getting
  the merger of the mpt2/mpt3sas driver, which was seen as an essential
  item of maintenance work to do before the drivers diverge too much.
  Unfortunately, this caused a compile failure (detected by linux-next),
  which then had to be fixed up and incubated.

  In addition to the mpt2/3sas rework, there are updates from pm80xx,
  lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
  an assortment of changes including some year 2038 issues, a fix for a
  remove before detach issue in some drivers and a couple of other minor
  issues"

scsi: use host wide tags by default

2015-11-10T01:11:57+00:00

This patch changes the !blk-mq path to the same defaults as the blk-mq
I/O path by always enabling block tagging, and always using host wide
tags.  We've had blk-mq available for a few releases so bugs with
this mode should have been ironed out, and this ensures we get better
coverage of over tagging setup over different configs.
