[PATCH] raw1394: fix locking in the presence of SMP and interrupts

2005-10-20T06:04:30+00:00

Changes all spinlocks that can be held during an irq handler to disable
interrupts while the lock is held.  Changes spin_[un]lock_irq to use the
irqsave/irqrestore variants for robustness and readability.

In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're
not accessing host_info_list or host_count, and holding this lock while
trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if
ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in
raw1394.c:receive_iso.  Test program attached reliably deadlocks all SMP
machines I have been able to test without this patch.

[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.

needed nowadays.

Use of time_before() macro, defined at linux/jiffies.h, which deal with
wrapping correctly and are nicer to read.

[PATCH] ieee1394: fix for debug output

2005-09-30T19:41:19+00:00

Fix debug code so it prints the correct speed (was defaulting to 100, so
anything > 400 showed only 100).

[PATCH] ieee1394: skip unnecessary pause when scanning config ROMs

2005-09-30T19:41:19+00:00

Skip a superfluous pause that occured when the config ROM of a node was
scanned unsuccessfully.  This also occurs if a node without link wrongly
enables its "link active" self ID flag.  A GWCTech 6-port hub does this.
