-
Dmitry Adamushko authored
Commit f18f982a ("sched: CPU hotplug events must not destroy scheduler domains created by the cpusets") introduced a hotplug-related problem as described below: Upon CPU_DOWN_PREPARE, update_sched_domains() -> detach_destroy_domains(&cpu_online_map) does the following: /* * Force a reinitialization of the sched domains hierarchy. The domains * and groups cannot be updated in place without racing with the balancing * code, so we temporarily attach all running cpus to the NULL domain * which will prevent rebalancing while the sched domains are recalculated. */ The sched-domains should be rebuilt when a CPU_DOWN ops. has been completed, effectively either upon CPU_DEAD{_FROZEN} (upon success) or CPU_DOWN_FAILED{_FROZEN} (upon failure -- restore the things to their initial state). That's what update_sched_domains() also does but only for !CPUSETS case. With f18f982a, sched-domains' reinitialization is delegated to CPUSETS code: cpuset_handle_cpuhp() -> common_cpu_mem_hotplug_unplug() -> rebuild_sched_domains() Being called for CPU_UP_PREPARE and if its callback is called after update_sched_domains()), it just negates all the work done by update_sched_domains() -- i.e. a soon-to-be-offline cpu is included in the sched-domains and that makes it visible for the load-balancer while the CPU_DOWN ops. is in progress. __migrate_live_tasks() moves the tasks off a 'dead' cpu (it's already "offline" when this function is called). try_to_wake_up() is called for one of these tasks from another CPU -> the load-balancer (wake_idle()) picks up a "dead" CPU and places the task on it. Then e.g. BUG_ON(rq->nr_running) detects this a bit later -> oops. Signed-off-by:

The current definition of wksidarr works fine on little endian arches (since cpu_to_le32 is a no-op there), but on big-endian arches, it fails to compile with this error: error: braced-group within expression allowed only inside a function The problem is that this static declaration has cpu_to_le32 embedded within it, and that expands into a function macro. We need to use __constant_cpu_to_le32() instead. Signed-off-by:

Try this: mount a share with unix extensions create a file on it umount the share You'll get the following message in the ring buffer: VFS: Busy inodes after unmount of cifs. Self-destruct in 5 seconds. Have a nice day... ...the problem is that cifs_get_inode_info_unix is creating and hashing a new inode even when it's going to return error anyway. The first lookup when creating a file returns an error so we end up leaking this inode before we do the actual create. This appears to be a regression caused by commit 0e4bbde9. The following patch seems to fix it for me, and fixes a minor formatting nit as well. Signed-off-by:Steven French <sfrench@us.ibm.com> Signed-off-by:

Cortland Setlow pointed out a bug in ov7670.c where the result from ov7670_read() was just being checked for !0, rather than <0. This made me realize that ov7670_read's semantics were rather confusing; it both fills in 'value' with the result, and returns it. This is goes against general kernel convention; so rather than fixing callers, let's fix the function. This makes ov7670_read return <0 in the case of an error, and 0 upon success. Thus, code like: res = ov7670_read(...); if (!res) goto error; ..will work properly. Signed-off-by:

I had 8250.nr_uarts=16 in the boot line of a test kernel and I had a weird mysterious crash in sysfs. After taking an in-depth look I realized that CONFIG_SERIAL_8250_NR_UARTS was set to 4 and I was walking off the end of the serial8250_ports array. Ouch!!! Don't let this happen to someone else.
