[PATCH] packet writing oops fix

2005-11-24T22:10:07+00:00

There is an old bug in the pkt_count_states() function that causes stack
corruption.  When compiling with gcc 3.x or 2.x it is harmless, but gcc 4
allocates local variables differently, which makes the bug visible.

Don't clear ->elevator_data on exit, if we are switching queues we are
overwriting the data of the new io scheduler.

[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57+00:00

 - added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.

[PATCH] scsi_ioctl: only warn for rejected commands

2005-10-08T22:00:57+00:00

We should not be warning about commands that we allow, even if they are
unknown. So move the if-root-allow check up a notch.

[PATCH] ub: Comment out unconditional stall clear

2005-09-22T14:58:26+00:00

This code appears to be more trouble than it's worth, considering that
no normal users reload drivers. So, we comment it for now. It is not
removed outright for the benefit of hackers (that is, myself).

[PATCH] ub: fix burning cds

2005-09-22T14:58:25+00:00

This patch fixes a few problems with ub and cleans up a couple of things:

 - Bump UB_MAX_REQ_SG, this allows to burn CDs
 - Drop initialization of urb.transfer_flags,
   now that URB_UNLINK_ASYNC is gone
 - Add forgotten processing of stalls at GetMaxLUN
 - Remove a few more P3-tagged printks whose time has come
 - Correct comment about ZIP-100

It is a feeble attempt at fixing the request handling in pf, it is totally
foobar right now.
