[PATCH 10/12] perf: make nr_events an int and add perf_online_mutex to protect it
Change nr_events from atomic_t to int and add perf_online_mutex to protect it. Helpers to manipulate the count, perf_inc_nr_events() and perf_dec_nr_events(), are added. The former may fail although it doesn't in the current code. This will be used to make sched perf functions called via tracepoints. Signed-... 4 May 2010 08:59

[PATCH] perf: Fix performance issue with perf report
On a large machine we spend a lot of time in perf_header__find_attr when running perf report. If we are parsing a file without PERF_SAMPLE_ID then for each sample we call perf_header__find_attr and loop through all counter IDs, never finding a match. As the machine gets larger there are more per cpu counters a... 4 May 2010 07:53
[PATCH -V2 0/2] fix oom happening when changing cpuset'mems(was: [regression] cpuset,mm: update tasks' mems_allowed in time (58568d2))
Nick Piggin reported that the allocator may see an empty nodemask when changing cpuset's mems[1]. It happens only on the kernel that do not do atomic nodemask_t stores. (MAX_NUMNODES > BITS_PER_LONG) But I found that there is also a problem on the kernel that can do atomic nodemask_t stores. The problem is that t... 4 May 2010 07:53

[PATCH 2/7] oprofile/x86: rework error handler in nmi_setup()
This patch improves the error handler in nmi_setup(). Most parts of the code are moved to allocate_msrs(). In case of an error allocate_msrs() also frees already allocated memory. nmi_setup() becomes easier and better extendable.
