This is addressed in the first patch. Furthermore max_threads is checked against FUTEX_TID_MASK._ The calculation of max_threads is moved to a separate function. The second patch addresses max_threads being set by writing to /proc/sys/kernel/threads-max. The same limits are applied as in fork_init. The third patch uses a callback function to updated max_thread when a memory hotplug event occurs. New in version 3: Determination of max_threads moved to separate function. Handling of /proc/sys/kernel/threads-max Handling of memory hotplugging.
