The documented[1] behavior of sched_attr() in the proposed man page text is: sched_attr::size must be set to the size of the structure, as in sizeof(struct sched_attr), if the provided structure is smaller than the kernel structure, any additional fields are assumed '0'. If the provided structure is larger than the kernel structure, the kernel verifies all additional fields are '0' if not the syscall will fail with -E2BIG. As currently implemented, sched_copy_attr() returns -EFBIG for for this case, but the logic in sys_sched_setattr() converts that error to -EFAULT. This patch fixes the behavior.

The following commit: e5fc6611 ("sched: Fix race in idle_balance()") can potentially cause rq->max_idle_balance_cost to not be updated, even when load_balance(NEWLY_IDLE) is attempted and the per-sd max cost value is updated. Preeti noticed a similar issue with updating rq->next_balance. In this patch, we fix this by making sure we still check/update those values even if a task gets enqueued while browsing the domains.

Tim wrote: "The current code will call pick_next_task_fair a second time in the slow path if we did not pull any task in our first try. This is really unnecessary as we already know no task can be pulled and it doubles the delay for the cpu to enter idle. We instrumented some network workloads and that saw that pick_next_task_fair is frequently called twice before a cpu enters idle. The call to pick_next_task_fair can add non trivial latency as it calls load_balance which runs find_busiest_group on an hierarchy of sched domains spanning the cpus for a large system. For some 4 socket systems, we saw almost 0.25 msec spent per call of pick_next_task_fair before a cpu can be idled." Optimize the second call away for the common case and document the dependency.

The check at the beginning of cpupri_find() makes sure that the task_pri variable does not exceed the cp->pri_to_cpu array length. But that length is CPUPRI_NR_PRIORITIES not MAX_RT_PRIO, where it will miss the last two priorities in that array. As task_pri is computed from convert_prio() which should never be bigger than CPUPRI_NR_PRIORITIES, if the check should cause a panic if it is hit.

yield_task_dl() is broken: o it forces current to be throttled setting its runtime to zero; o it sets current's dl_se->dl_new to one, expecting that dl_task_timer() will queue it back with proper parameters at replenish time. Unfortunately, dl_task_timer() has this check at the very beginning: if (!dl_task(p) || dl_se->dl_new) goto unlock; So, it just bails out and the task is never replenished. It actually yielded forever. To fix this, introduce a new flag indicating that the task properly yielded the CPU before its current runtime expired. While this is a little overdoing at the moment, the flag would be useful in the future to discriminate between "good" jobs (of which remaining runtime could be reclaimed, i.e. recycled) and "bad" jobs (for which dl_throttled task has been set) that needed to be stopped.

Russell reported, that irqtime_account_idle_ticks() takes ages due to: for (i = 0; i < ticks; i++) irqtime_account_process_tick(current, 0, rq); It's sad, that this code was written way _AFTER_ the NOHZ idle functionality was available. I charge myself guitly for not paying attention when that crap got merged with commit abb74cef ("sched: Export ns irqtimes through /proc/stat") So instead of looping nr_ticks times just apply the whole thing at once. As a side note: The whole cputime_t vs. u64 business in that context wants to be cleaned up as well. There is no point in having all these back and forth conversions. Lets standardise on u64 nsec for all kernel internal accounting and be done with it. Everything else does not make sense at all for fine grained accounting.

Inferring the mount hierarchy correctly from /proc/mounts is hard when MS_MOVE may have been used, and the previous code did it wrongly. This change simplifies the logic to only require that /dev/shm be _on_ tmpfs (which can be checked trivially with statfs) rather than that it be a _mountpoint_ of tmpfs, since there isn't a compelling reason to be that strict. We also now check for tmpfs on whatever directory we ultimately use so that the user is better informed. This change also moves the more standard TMPDIR environment variable check ahead of the others. Applies to 3.12.

In the current version, when using perf record, if something goes wrong in tools/perf/builtin-record.c:375 session = perf_session__new(file, false, NULL); The error message: "Not enough memory for reading per file header" is issued. This error message seems to be outdated and is not very helpful. This patch proposes to replace this error message by "Perf session creation failed" I believe this issue has been brought to lkml: https://lkml.org/lkml/2014/2/24/458 although this patch only tackles a (small) part of the issue. Additionnaly, this patch improves error reporting in tools/perf/util/data.c open_file_write. Currently, if the call to open fails, the user is unaware of it. This patch logs the error, before returning the error code to the caller.

Every event in the perf-kvm has a 'stats' structure, which contains max/min/average/etc times of handling this event. The problem is that the 'perf-kvm stat report' command always shows that 'min time' is 0us for every event. Example: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 0us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 0us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 0us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 0us 44us 16.49us ( +- 38.20% ) [..] This happens because the 'stats' structure is not initialized and stats->min equals to 0. Lets initialize the structure for every event after its allocation using init_stats() function. This initializes stats->min to -1 and makes 'Min time' statistics counting work: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 6us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 7us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 1us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 1us 44us 16.49us ( +- 38.20% ) [..] Signed-off-by: NAlexander Yarygin <yarygin@linux.vnet.ibm.com> Signed-off-by: NChristian Borntraeger <borntraeger@de.ibm.com> Reviewed-by: NDavid Ahern <dsahern@gmail.com> Link: http://lkml.kernel.org/r/1397053319-2130-3-git-send-email-borntraeger@de.ibm.com [ Fixing the perf examples changelog output ] Signed-off-by: NJiri Olsa <jolsa@redhat.com>

When formatting with 1KB or 2KB(not aligned with PAGE SIZE) block size, xfstests generic/075 and 091 are failing. The offset supplied to function truncate_pagecache_range is block size aligned. In this function start offset is re-aligned to PAGE_SIZE by rounding_up to the next page boundary. Due to this rounding up, old data remains in the page cache when blocksize is less than page size and start offset is not aligned with page size. In case of collapse range, we need to align start offset to page size boundary by doing a round down operation instead of round up.
