2006-08-06[SCSI] scsi_queue_work() documented return value is incorrectMichael Reed1-1/+3
If you examine the queue_work() routine you'll see that it returns 1 on success, 0 if the work is already queued. This patch corrects the source code documentation for the scsi_queue_work function.

2006-08-02[SCSI] arcmsr: fix up sysfs valuesJames Bottomley1-10/+10
The sysfs files in arcmsr are non-standard in that they aren't simple filename value pairs, the values actually contain preceeding text which would have to be parsed. The idea of sysfs files is that the file name is the description and the contents is a simple value. Fix up arcmsr to conform to this standard.

2006-07-26[PATCH] fix compile regression for a few scsi driversChristoph Hellwig2-12/+6
This fixes three drivers to compile again after my patch that removes the data_cmnd member from struct scsi_cmnd. The fas216 change is trivial, it should have been using ->cmnd all the time. NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing something odd, it should only have looked at ->cmnd before not the saved copy that is kept for the error handlers sake. Note that it really should deal with the sync setting themselves but use the generic domain validation code that get this right - but that's for later let's push this simple compile fix for now. And sorry for the late fix for this, I have been busy with OLS and associated activities last week. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-07-26[PATCH] Reorganize the cpufreq cpu hotplug locking to not be totally bizareArjan van de Ven5-29/+23
The patch below moves the cpu hotplugging higher up in the cpufreq layering; this is needed to avoid recursive taking of the cpu hotplug lock and to otherwise detangle the mess. The new rules are: 1. you must do lock_cpu_hotplug() around the following functions: __cpufreq_driver_target __cpufreq_governor (for CPUFREQ_GOV_LIMITS operation only) __cpufreq_set_policy 2. governer methods (.governer) must NOT take the lock_cpu_hotplug() lock in any way; they are called with the lock taken already 3. if your governer spawns a thread that does things, like calling __cpufreq_driver_target, your thread must honor rule #1. 4. the policy lock and other cpufreq internal locks nest within the lock_cpu_hotplug() lock. I'm not entirely happy about how the __cpufreq_governor rule ended up (conditional locking rule depending on the argument) but basically all callers pass this as a constant so it's not too horrible. The patch also removes the cpufreq_governor() function since during the locking audit it turned out to be entirely unused (so no need to fix it) The patch works on my testbox, but it could use more testing (otoh... it can't be much worse than the current code) Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-07-26[IPV4/IPV6]: Setting 0 for unused port field in RAW IP recvmsg().Tetsuo Handa2-0/+2
From: Tetsuo Handa from-linux-kernel@i-love.sakura.ne.jp The recvmsg() for raw socket seems to return random u16 value from the kernel stack memory since port field is not initialized. But I'm not sure this patch is correct. Does raw socket return any information stored in port field? [ BSD defines RAW IP recvmsg to return a sin_port value of zero.

Locally generated broadcast and multicast packets have pkttype set to PACKET_LOOPBACK instead of PACKET_BROADCAST or PACKET_MULTICAST. This causes the pkttype match to fail to match packets of either type. The below patch remedies this by using the daddr as a hint as to broadcast|multicast.
