While the !highres/!dyntick code assigns the duty of the do_timer() call to one specific CPU, this was dropped in the highres/dyntick part during development. Steven Rostedt discovered the xtime lock contention on highres/dyntick due to several CPUs trying to update jiffies. Add the single CPU assignement back. In the dyntick case this needs to be handled carefully, as the CPU which has the do_timer() duty must drop the assignement and let it be grabbed by another CPU, which is active. Otherwise the do_timer() calls would not happen during the long sleep. Signed-off-by:

Johannes Berg reported that struct names are not highlighted (bold, italic, etc.) in html kernel-doc output. (Also not in text-mode output, but I don't see that changing.) This patch adds the following: - highlight struct names in html output mode - highlight environment var. names in html output mode - indent struct fields in the original struct layout Signed-off-by:

notify_change() already calls security_inode_setattr() before calling iop->setattr. Alan sayeth This is a behaviour change on all of these and limits some behaviour of existing established security modules When inode_change_ok is called it has side effects. This includes clearing the SGID bit on attribute changes caused by chmod. If you make this change the results of some rulesets may be different before or after the change is made. I'm not saying the change is wrong but it does change behaviour so that needs looking at closely (ditto all other attribute twiddles) Signed-off-by:

We've had various reports of some legacy "probe the hardware" style platform drivers having nasty problems with hotplug support. The core issue is that those legacy drivers don't fully conform to the driver model. They assume a role that should be the responsibility of infrastructure code: creating device nodes. The "modprobe" step in hotplugging relies on drivers to have split those roles into different modules. The lack of this split causes the problems. When a driver creates nodes for devices that don't exist (sending a hotplug event), then exits (aborting one modprobe) before the "modprobe $MODALIAS" step completes (by failing, since it's in the middle of a modprobe), the result can be an endless loop of modprobe invocations ... badness. This fix uses the newish per-device flag controlling issuance of "add" events. (A previous version of this patch used a per-device "driver can hotplug" flag, which only scrubbed $MODALIAS from the environment rather than suppressing the entire hotplug event.) It also shrinks that flag to one bit, saving a word in "struct device". So the net of this patch is removing some nasty failures with legacy drivers, while retaining hotplug capability for the majority of platform drivers. Signed-off-by:

Set rq->errors more correctly in cciss driver. Previously we had set it synonymously with the meaning of the last parameter of end_that_last_request and complete_buffers (the "uptodate" parameter) and had gotten away with it for all this time because nobody ever looked at rq->errors. SCSI_IOCTL_SEND_COMMAND looks at rq->errors, so now it matters that it be right. Signed-off-by:

For all of you that think cciss should be a scsi driver here is the patch that you have been waiting for all these years. This patch actually adds the SG_IO ioctl to cciss. The primary purpose is for clustering and high-availibilty. But now anyone can exploit this ioctl in any manner they wish. Note, SCSI_IOCTL_SEND_COMMAND doesn't work with this patch due to rq->errors being set incorrectly. Subsequent patch fixes that. Signed-off-by:

This patch fixes two things in module_init. - fix register_chrdev() error check Currently dtlk doesn't check register_chrdev() failure correctly. register_chrdev() returns a errno on failure. - check probe failure dtlk ignores probe failure and allows the module loading without such device. I got "Trying to free nonexistent resource" message by release_region() when unloading module without device. [akpm@linux-foundation.org: fix error code return] Signed-off-by:

We noticed a drop in n/w performance due to the irq_desc being cacheline aligned rather than internode aligned. We see 50% of expected performance when two e1000 nics local to two different nodes have consecutive irq descriptors allocated, due to false sharing. Note that this patch does away with cacheline padding for the UP case, as it does not seem useful for UP configurations. Signed-off-by:

In a different approach here's a patch that handles the special case of composite arithmetic expressions in array size initializers. With it, prior to pushing the split strings on the @first_arg array, I split the keywords before the array name as before and then keep the array name along with the subscript expression as a single whole element which gets pushed last. In this manner, kernel-doc produces correct output without removing whitespaces which makes the array subscripts unreadable in the docs. Signed-off-by:
