Note that these includes are recent addition caused by added inline function that had since then become a define. So while I agree with your comments in general, in _this_ case it's pretty safe. The commit that had done it is 3062fc67dad01b1d2a15d58c709eff946389eca4 ("memcontrol: move mm_cgroup to header file") and the switch to #define is in commit 60c12b1202a60eabb1c61317e5d2678fcea9893f ("memcontrol: add vm_match_cgroup()") (BTW, that probably warranted mentioning in the changelog of the latter).

* hugetlb: ensure we do not reference a surplus page after handing it to buddyAndy Whitcroft2008-02-23
| | | | | | | | | | | | | | | | | | When we free a page via free_huge_page and we detect that we are in surplus the page will be returned to the buddy. After this we no longer own the page. However at the end free_huge_page we clear out our mapping pointer from page private. Even where the page is not a surplus we free the page to the hugepage pool, drop the pool locks and then clear page private. In either case the page may have been reallocated. BAD. Make sure we clear out page private before we free the page.

| * [SCSI] aic94xx: fix sequencer hang on error recoveryJames Bottomley2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The clear nexus I_T and clear nexus I_T_L functions in the aic94xx specify the SUSPEND_TX flag which causes the sequencer to be suspended until it receives a RESUME_TX. Unfortunately, nothing ever sends the resume, so the sequencer on the link is stopped forever, leading to eventual timeouts and I/O errors. Since clear nexus commands are only executed as part of error recovery, it's perfectly fine to keep the sequencer running on the link ... as soon as the recovery function is completed, we'll send it the commands to retry.

| * [SCSI] stex: stex_internal_copy should be called with sg_count in struct st_ccbFUJITA Tomonori2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | stex_internal_copy copies an in-kernel buffer to a sg list by using scsi_kmap_atomic_sg. Some functions calls stex_internal_copy with sg_count in struct st_ccb, which is the value that dma_map_sg returned. However it might be shorter than the actual number of sg entries (if the IOMMU merged the sg entries). scsi_kmap_atomic_sg doesn't see sg->dma_length so stex_internal_copy should be called with the actual number of sg entries (i.e. scsi_sg_count), because if the sg entries were merged, stex_direct_copy wrongly think that the data length in the sg list is shorter than the actual length.

| * [SCSI] stex: stex_direct_copy shouldn't call dma_map_sgFUJITA Tomonori2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | stex_direct_copy copies an in-kernel buffer to a sg list in order to spoof some SCSI commands. stex_direct_copy calls dma_map_sg and then stex_internal_copy with the value that dma_map_sg returned. It calls scsi_kmap_atomic_sg to copy data. scsi_kmap_atomic_sg doesn't see sg->dma_length so if dma_map_sg merges sg entries, stex_internal_copy gets the smaller number of sg entries than the acutual number, which means it wrongly think that the data length in the sg list is shorter than the actual length. stex_direct_copy shouldn't call dma_map_sg and it doesn't need since this code path doesn't involve dma transfers. This patch removes stex_direct_copy and simply calls stex_internal_copy with the actual number of sg entries.

| * [SCSI] libsas: fix error handlingJames Bottomley2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The libsas error handler has two fairly fatal bugs 1. scsi_sas_task_done calls scsi_eh_finish_cmd() too early. This happens if the task completes after it has been aborted but before the error handler starts up. Because scsi_eh_finish_cmd() decrements host_failed and adds the task to the done list, the error handler start check (host_failed == host_busy) never passes and the eh never starts. 2. The multiple task completion paths sas_scsi_clear_queue_... all simply delete the task from the error queue. This causes it to disappear into the ether, since a command must be placed on the done queue to be finished off by the error handler. This behaviour causes the HBA to hang on pending commands. Fix 1. by moving the SAS_TASK_STATE_ABORTED check to an exit clause at the top of the routine and calling ->scsi_done() unconditionally (it is a nop if the timer has fired). This keeps the task in the error handling queue until the eh starts. Fix 2. by making sure every task goes through task complete followed by scsi_eh_finish_cmd(). Tested this by firing resets across a disk running a hammer test (now it actually survives without hanging the system) Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| * [SCSI] aic94xx: fix REQ_TASK_ABORT and REQ_DEVICE_RESETJames Bottomley2008-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver has been failing under heavy load with aic94xx: escb_tasklet_complete: REQ_TASK_ABORT, reason=0x6 aic94xx: escb_tasklet_complete: Can't find task (tc=4) to abort! The second message is because the driver fails to identify the task it's being asked to abort. On closer inpection, there's a thinko in the for each task loop over pending tasks in both the REQ_TASK_ABORT and REQ_DEVICE_RESET cases where it doesn't look at the task on the pending list but at the one on the ESCB (which is always NULL). Fix by looking at the right task. Also add a print for the case where the pending SCB doesn't have a task attached. Not sure if this will fix all the problems, but it's a definite first step.

* | percpu: fix DEBUG_PREEMPT per_cpu checkingHugh Dickins2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.25-rc1 percpu changes broke CONFIG_DEBUG_PREEMPT's per_cpu checking on several architectures. On s390, sparc64 and x86 it's been weakened to not checking at all; whereas on powerpc64 it's become too strict, issuing warnings from __raw_get_cpu_var in io_schedule and init_timer for example. Fix this by weakening powerpc's __my_cpu_offset to use the non-checking local_paca instead of get_paca (which itself contains such a check); and strengthening the generic my_cpu_offset to go the old slow way via smp_processor_id when CONFIG_DEBUG_PREEMPT (debug_smp_processor_id is where all the knowledge of what's correct when lives).

* | PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.
