Instead of only considering SD_WAKE_AFFINE | SD_PREFER_SIBLING domains also allow all SD_PREFER_SIBLING domains below a SD_WAKE_AFFINE domain to change the affinity target.

Originally task_s/utime() were designed to return clock_t but later changed to return cputime_t by following commit: commit efe567fc Author: Christian Borntraeger <borntraeger@de.ibm.com> Date: Thu Aug 23 15:18:02 2007 +0200 It only changed the type of return value, but not the implementation. As the result the granularity of task_s/utime() is still that of clock_t, not that of cputime_t. So using task_s/utime() in __exit_signal() makes values accumulated to the signal struct to be rounded and coarse grained. This patch removes casts to clock_t in task_u/stime(), to keep granularity of cputime_t over the calculation. v2: Use div_u64() to avoid error "undefined reference to `__udivdi3`" on some 32bit systems.

From the code in rt_mutex_setprio(), it is evident that the intention is that task's with a RT 'prio' value as a consequence of receiving a PI boost also have their 'sched_class' field set to '&rt_sched_class'. However, Peter noticed that the code in __setscheduler() could result in this intention being frustrated. Fix it.

Commit 1b9508f6, "Rate-limit newidle" has been confirmed to fix the netperf UDP loopback regression reported by Alex Shi. This is a cleanup and a fix: - moved to a more out of the way spot - fix to ensure that balancing doesn't try to balance runqueues which haven't gone online yet, which can mess up CPU enumeration during boot.

When waking affine, check for an idle shared cache, and if found, wake to that CPU/sibling instead of the waker's CPU. This improves pgsql+oltp ramp up by roughly 8%.

Currently partition_sched_domains() takes a 'struct cpumask *doms_new' which is a kmalloc'ed array of cpumask_t. You can't have such an array if 'struct cpumask' is undefined, as we plan for CONFIG_CPUMASK_OFFSTACK=y. So, we make this an array of cpumask_var_t instead: this is the same for the CONFIG_CPUMASK_OFFSTACK=n case, but requires multiple allocations for the CONFIG_CPUMASK_OFFSTACK=y case. Hence we add alloc_sched_domains() and free_sched_domains() functions.

CPU time of a guest is always accounted in 'user' time without concern for the nice value of its counterpart process although the guest is scheduled under the nice value. This patch fixes the defect and accounts cpu time of a niced guest in 'nice' time as same as a niced process. And also the patch adds 'guest_nice' to cpuacct. The value provides niced guest cpu time which is like 'nice' to 'user'.

Rusty, commit 3ca4f5ca virtio: add virtio IDs file moved all device IDs into a single file. While the change itself is a very good one, it can break userspace applications. For example if a userspace tool wanted to get the ID of virtio_net it used to include virtio_net.h. This does no longer work, since virtio_net.h does not include virtio_ids.h. This patch moves all "#include <linux/virtio_ids.h>" from the C files into the header files, making the header files compatible with the old ones. In addition, this patch exports virtio_ids.h to userspace.

It seems like the addition of QUEUE_FLAG_VIRT caueses major performance regressions for Fedora users: https://bugzilla.redhat.com/show_bug.cgi?id=509383 https://bugzilla.redhat.com/show_bug.cgi?id=505695 while I can't reproduce those extreme regressions myself I think the flag is wrong. Rationale: QUEUE_FLAG_VIRT expands to QUEUE_FLAG_NONROT which casus the queue unplugged immediately. This is not a good behaviour for at least qemu and kvm where we do have significant overhead for every I/O operations. Even with all the latested speeups (native AIO, MSI support, zero copy) we can only get native speed for up to 128kb I/O requests we already are down to 66% of native performance for 4kb requests even on my laptop running the Intel X25-M SSD for which the QUEUE_FLAG_NONROT was designed. If we ever get virtio-blk overhead low enough that this flag makes sense it should only be set based on a feature flag set by the host.

For example: static int pipe_rdwr_open(struct inode *inode, struct file *filp) { msleep(100); mutex_lock(&inode->i_mutex); Although the defect was observed in pipe_rdwr_open(), I think it makes sense to replicate the change through all the pipe_*_open() functions. The core of the change is to verify that inode->i_pipe has not been released before attempting to manipulate it. If inode->i_pipe is no longer present, return ENOENT to indicate so. The comment about potentially using atomic_t for i_pipe->readers and i_pipe->writers has also been removed because it is no longer relevant in this context. The inode->i_mutex lock must be used so that inode->i_pipe can be dealt with correctly.

In ks8851_set_rx_mode() the case handling IFF_MULTICAST was also setting the RXCR1_AE bit by accident. This meant that all unicast frames where being accepted by the device. Remove RXCR1_AE from this case. Note, RXCR1_AE was also masking a problem with setting the MAC address properly, so needs to be applied after fixing the MAC write order.

Mask off FS_EVENT_ON_CHILD in dnotify_handle_event(). Otherwise, when there is more than one watch on a directory and dnotify_should_send_event() succeeds, events with FS_EVENT_ON_CHILD set will trigger all watches and cause spurious events. This case was overlooked in commit e42e2773. #define _GNU_SOURCE #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <signal.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <string.h> static void create_event(int s, siginfo_t* si, void* p) { printf("create\n"); } static void delete_event(int s, siginfo_t* si, void* p) { printf("delete\n"); } int main (void) { struct sigaction action; char *tmpdir, *file; int fd1, fd2; sigemptyset (&action.sa_mask); action.sa_flags = SA_SIGINFO; action.sa_sigaction = create_event; sigaction (SIGRTMIN + 0, &action, NULL); action.sa_sigaction = delete_event; sigaction (SIGRTMIN + 1, &action, NULL); # define TMPDIR "/tmp/test.XXXXXX" tmpdir = malloc(strlen(TMPDIR) + 1); strcpy(tmpdir, TMPDIR); mkdtemp(tmpdir); # define TMPFILE "/file" file = malloc(strlen(tmpdir) + strlen(TMPFILE) + 1); sprintf(file, "%s/%s", tmpdir, TMPFILE); fd1 = open (tmpdir, O_RDONLY); fcntl(fd1, F_SETSIG, SIGRTMIN); fcntl(fd1, F_NOTIFY, DN_MULTISHOT | DN_CREATE); fd2 = open (tmpdir, O_RDONLY); fcntl(fd2, F_SETSIG, SIGRTMIN + 1); fcntl(fd2, F_NOTIFY, DN_MULTISHOT | DN_DELETE); if (fork()) { /* This triggers a create event */ creat(file, 0600); /* This triggers a create and delete event (!) */ unlink(file); } else { sleep(1); rmdir(tmpdir); } return 0; } Signed-off-by: NAndreas Gruenbacher <agruen@suse.de> Signed-off-by: NEric Paris <eparis@redhat.com>
