From c8d9c90c7ece28259436476a016cdecd25dccf2c Mon Sep 17 00:00:00 2001 From: Paul Jackson Date: Thu, 7 Feb 2008 00:14:46 -0800 Subject: [PATCH] hotplug cpu: move tasks in empty cpusets to parent various other fixes Various minor formatting and comment tweaks to Cliff Wickman's [PATCH_3_of_3]_cpusets__update_cpumask_revision.patch I had had "iff", meaning "if and only if" in a comment. However, except for ancient mathematicians, the abbreviation "iff" was a tad too cryptic. Cliff changed it to "if", presumably figuring that the "iff" was a typo. However, it was the "only if" half of the conjunction that was most interesting. Reword to emphasis the "only if" aspect. The locking comment for remove_tasks_in_empty_cpuset() was wrong; it said callback_mutex had to be held on entry. The opposite is true. Several mentions of attach_task() in comments needed to be changed to cgroup_attach_task(). A comment about notify_on_release was no longer relevant, as the line of code it had commented, namely: set_bit(CS_RELEASED_RESOURCE, &parent->flags); is no longer present in that place in the cpuset.c code. Similarly a comment about notify_on_release before the scan_for_empty_cpusets() routine was no longer relevant. Removed extra parentheses and unnecessary return statement. Renamed attach_task() to cpuset_attach() in various comments. Removed comment about not needing memory migration, as it seems the migration is done anyway, via the cpuset_attach() callback from cgroup_attach_task().
