This patch makes the following minor updates to the cpuset partition testing script test_cpuset_prs.sh. - Remove online_cpus function call as it will be called anyway on exit in cleanup. - Make the enabling of sched/verbose debugfs flag conditional on the "-v" verbose option and set DELAY_FACTOR to 2 in this case as cpuset partition operations are likely to be slowed down by enabling that.

Similar to commit 3fb906e7 ("group/cpuset: Don't filter offline CPUs in cpuset_cpus_allowed() for top cpuset tasks"), the whole set of possible CPUs including offline ones should be used for setting cpumasks for tasks in the top cpuset when a cpuset partition is modified as the hotplug code won't update cpumasks for tasks in the top cpuset when CPUs become online or offline.

If a hotplug event doesn't affect the current cpuset, there is no point to call hotplug_update_tasks() or hotplug_update_tasks_legacy(). So just skip it. Signed-off-by:

It was found that commit 7a2127e6 ("cpuset: Call set_cpus_allowed_ptr() with appropriate mask for task") introduced a bug that corrupted "cpuset.cpus" of a partition root when it was updated. It is because the tmp->new_cpus field of the passed tmp parameter of update_parent_subparts_cpumask() should not be used at all as it contains important cpumask data that should not be overwritten. Fix it by using tmp->addmask instead. Also update update_cpumask() to make sure that trialcs->cpu_allowed will not be corrupted until it is no longer needed. Fixes: 7a2127e6 ("cpuset: Call set_cpus_allowed_ptr() with appropriate mask for task") Signed-off-by:

Commit 002f2906 ("cpuset: use static key better and convert to new API") has used __cpuset_node_allowed() instead of cpuset_node_allowed() to check whether we can allocate on a memory node. Now this function isn't used by anyone, so we can do the follow things to clean up it. 1. remove unused codes 2. rename __cpuset_node_allowed() to cpuset_node_allowed() 3. update comments in mm/page_alloc.c Suggested-by:

We need to reset forceidle_sum to 0 when reading from root, since the bstat we accumulate into is stack allocated. To make this more robust, just replace the existing cputime reset with a memset of the overall bstat. Signed-off-by:

Before commit bdc1ddad ("compat_ioctl: block: move blkdev_compat_ioctl() into ioctl.c"), the config BLOCK_COMPAT was used to include compat_ioctl.c into the kernel build. With this commit, the code is moved into ioctl.c and included with the config COMPAT. So, since then, the config BLOCK_COMPAT has no effect and any further purpose. Remove this obsolete config BLOCK_COMPAT. Signed-off-by:

The reason is that we try to drop excessive references with folio_put_refs(), but pages were acquired with pin_user_pages(), which has extra accounting and so should be put down with matching unpin_user_pages() or at least gup_put_folio(). As a fix unpin_user_pages() all but first page instead, and let's figure out a better API after. Fixes: 57bebf80 ("io_uring/rsrc: optimise registered huge pages") Reported-by:

msg_ring requests transferring files support auto index selection via IORING_FILE_INDEX_ALLOC, however they don't return the selected index to the target ring and there is no other good way for the userspace to know where is the receieved file. Return the index for allocated slots and 0 otherwise, which is consistent with other fixed file installing requests.
