Affine wakeups have the potential to interfere with NUMA placement.
If a task wakes up too many other tasks, affine wakeups will get
disabled.
However, regardless of how many other tasks it wakes up, it gets
re-enabled once a second, potentially interfering with NUMA
placement of other tasks.

task_hot checks exec_start on any runnable task, but if it has been
migrated since the it last ran, then exec_start is a clock_task from
another cpu. If the old cpu's clock_task was sufficiently far ahead of
this cpu's then the task will not be considered for another migration
until it has run. Ins

None of the callers pass in a NULL hnode so there isn't actually a NULL
dereference here. You could just remove the check.

Coming in v3.16, trace events will be able to save bitmasks in raw
format in the ring buffer and output it with the __get_bitmask() macro.
In order for userspace tools to parse this, it must be able to handle
the __get_bitmask() call and be able to convert the data that's in
the ring buffer into

Hi
I do not know, I'm not an expert on this code.
But since there before was a if (cred) someone must have thought this
could happen.

Fix the logic to allow overriding event default periods with -c or -F
on the command line. I'm not sure I understand this if() fully, but
this change makes all cases I tested work (tracepoint with default, default,
,-c, -F)
This fixed specifying -c / -F with json event list eve
