When a cpuset's nodemask is updated, all attached tasks have their cached task->mems_allowed updated by a heap instead of requiring an explicit call to cpuset_update_task_memory_state(), which has since been removed in 58568d2a ("cpuset,mm: update tasks' mems_allowed in time"). Remove the obsoleted comment from the page allocator. Cc: Paul Menage <menage@google.com> Acked-by:

In theory it could happen that on one CPU we initialize a new inode but clearing of I_NEW | I_LOCK gets reordered before some of the initialization. Thus on another CPU we return not fully uptodate inode from iget_locked(). This seems to fix a corruption issue on ext3 mounted over NFS.

NFS may free the server structure without ever having used the bdi, so we either need to flag the bdi as being uninitialized or initialize it up front. This does the latter. This fixes a crash with mounting more than one NFS file system, should people ever need that kind of obscure NFS functionality. Tested-by:

Bye-bye Performance Counters, welcome Performance Events! In the past few months the perfcounters subsystem has grown out its initial role of counting hardware events, and has become (and is becoming) a much broader generic event enumeration, reporting, logging, monitoring, analysis facility. Naming its core object 'perf_counter' and naming the subsystem 'perfcounters' has become more and more of a misnomer. With pending code like hw-breakpoints support the 'counter' name is less and less appropriate. All in one, we've decided to rename the subsystem to 'performance events' and to propagate this rename through all fields, variables and API names. (in an ABI compatible fashion) The word 'event' is also a bit shorter than 'counter' - which makes it slightly more convenient to write/handle as well. Thanks goes to Stephane Eranian who first observed this misnomer and suggested a rename. User-space tooling and ABI compatibility is not affected - this patch should be function-invariant. (Also, defconfigs were not touched to keep the size down.) This patch has been generated via the following script: FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/PERF_EVENT_/PERF_RECORD_/g' \ -e 's/PERF_COUNTER/PERF_EVENT/g' \ -e 's/perf_counter/perf_event/g' \ -e 's/nb_counters/nb_events/g' \ -e 's/swcounter/swevent/g' \ -e 's/tpcounter_event/tp_event/g' \ $FILES for N in $(find . -name perf_counter.[ch]); do M=$(echo $N | sed 's/perf_counter/perf_event/g') mv $N $M done FILES=$(find . -name perf_event.*) sed -i \ -e 's/COUNTER_MASK/REG_MASK/g' \ -e 's/COUNTER/EVENT/g' \ -e 's/\<event\>/event_id/g' \ -e 's/counter/event/g' \ -e 's/Counter/Event/g' \ $FILES ... to keep it as correct as possible. This script can also be used by anyone who has pending perfcounters patches - it converts a Linux kernel tree over to the new naming. We tried to time this change to the point in time where the amount of pending patches is the smallest: the end of the merge window. Namespace clashes were fixed up in a preparatory patch - and some stylistic fallout will be fixed up in a subsequent patch. ( NOTE: 'counters' are still the proper terminology when we deal with hardware registers - and these sed scripts are a bit over-eager in renaming them. I've undone some of that, but in case there's something left where 'counter' would be better than 'event' we can undo that on an individual basis instead of touching an otherwise nicely automated patch. ) Suggested-by:Stephane Eranian <eranian@google.com> Acked-by:

This is in preparation of the big rename, but also makes sense in a standalone way: 'list_entry' is a bad name as we already have a list_entry() in list.h. Also, the 'counter list' is too vague, it doesnt tell us the purpose of that list. Clarify these names to show that it's all about the group hiearchy. Acked-by:
