2011-07-25pagewalk: add locking-rule commentsKOSAKI Motohiro
Originally, walk_hugetlb_range() didn't require a caller take any lock. But commit d33b9f45bd ("mm: hugetlb: fix hugepage memory leak in walk_page_range") changed its rule. Because it added find_vma() call in walk_hugetlb_range(). Any locking-rule change commit should write a doc too.

2011-07-25pagewalk: don't look up vma if walk->hugetlb_entry is unusedKOSAKI Motohiro
Currently, walk_page_range() calls find_vma() every page table for walk iteration. but it's completely unnecessary if walk->hugetlb_entry is unused. And we don't have to assume find_vma() is a lightweight operation. So this patch checks the walk->hugetlb_entry and avoids the find_vma() call if possible. This patch also makes some cleanups. 1) remove ugly uninitialized_var() and 2) #ifdef in function body.

2011-07-25xen/balloon: memory hotplug support for Xen balloon driverDaniel Kiper
Memory hotplug support for Xen balloon driver. It should be mentioned that hotplugged memory is not onlined automatically. It should be onlined by user through standard sysfs interface. Memory could be hotplugged in following steps: 1) dom0: xl mem-max <domU> <maxmem> where <maxmem> is >= requested memory size, 2) dom0: xl mem-set <domU> <memory> where <memory> is requested memory size; alternatively memory could be added by writing proper value to /sys/devices/system/xen_memory/xen_memory0/target or /sys/devices/system/xen_memory/xen_memory0/target_kb on dumU, 3) domU: for i in /sys/devices/system/memory/memory*/state; do \ [ "`cat "$i"`" = offline ] && echo online > "$i"; done Memory could be onlined automatically on domU by adding following line to udev rules: SUBSYSTEM=="memory", ACTION=="add", RUN+="/bin/sh -c '[ -f /sys$devpath/state ] && echo online > /sys$devpath/state'" In that case step 3 should be omitted.

2011-07-25mm: extend memory hotplug API to allow memory hotplug in virtual machinesDaniel Kiper
This patch contains online_page_callback and apropriate functions for registering/unregistering online page callbacks. It allows to do some machine specific tasks during online page stage which is required to implement memory hotplug in virtual machines. Currently this patch is required by latest memory hotplug support for Xen balloon driver patch which will be posted soon. Additionally, originial online_page() function was splited into following functions doing "atomic" operations: - __online_page_set_limits() - set new limits for memory management code, - __online_page_increment_counters() - increment totalram_pages and totalhigh_pages, - __online_page_free() - free page to allocator. It was done to: - not duplicate existing code, - ease hotplug code devolpment by usage of well defined interface, - avoid stupid bugs which are unavoidable when the same code (by design) is developed in many places.

2011-07-25ipc/sem.c: fix race with concurrent semtimedop() timeouts and IPC_RMIDManfred Spraul
If a semaphore array is removed and in parallel a sleeping task is woken up (signal or timeout, does not matter), then the woken up task does not wait until wake_up_sem_queue_do() is completed. This will cause crashes, because wake_up_sem_queue_do() will read from a stale pointer. The fix is simple: Regardless of anything, always call get_queue_result(). This function waits until wake_up_sem_queue_do() has finished it's task.

The means that all accesses for stripe_head_state in handle_stripe[56] need to be 's->' instead of 's.', but the compiler should inline those functions and just use a direct stack reference, and future patches while hoist most of this code up into handle_stripe() so we will revert to "s.".

2011-07-26md/raid5: replace sh->lock with an 'active' flag.NeilBrown
sh->lock is now mainly used to ensure that two threads aren't running in the locked part of handle_stripe[56] at the same time. That can more neatly be achieved with an 'active' flag which we set while running handle_stripe. If we find the flag is set, we simply requeue the stripe for later by setting STRIPE_HANDLE. For safety we take ->device_lock while examining the state of the stripe and creating a summary in 'stripe_head_state / r6_state'. This possibly isn't needed but as shared fields like ->toread, ->towrite are checked it is safer for now at least. We leave the label after the old 'unlock' called "unlock" because it will disappear in a few patches, so renaming seems pointless. This leaves the stripe 'locked' for longer as we clear STRIPE_ACTIVE later, but that is not a problem. Signed-off-by: NeilBrown <neilb@suse.de> Reviewed-by: Namhyung Kim <namhyung@gmail.com>
