commit 920ef55d853b34d8f2fbe381e6cc8c1487bd3f20
Author: David Smith <dsmith@redhat.com>
Date: Thu May 3 14:20:34 2012 -0500
Improved task_finder2 mmap tracking and better task_work cleanup.
* runtime/task_finder2.c (__stp_tf_alloc_task_work): New function.
(__stp_tf_free_task_work): Ditto.
(__stp_tf_cancel_task_work): Ditto.
(__stp_tf_quiesce_worker): Renamed from __stp_task_worker(). Uses
__stp_tf_free_task_work() to free the task_work structure.
(__stp_utrace_task_finder_target_quiesce): Uses
__stp_tf_alloc_task_work() to allocate a task_work structure.
(__stp_tf_mmap_worker): New task_work worker function.
(__stp_utrace_task_finder_target_syscall_exit): If we're in an atomic
context, use task_work_add() to call __stp_tf_mmap_worker().
(stap_stop_task_finder): Call __stp_tf_cancel_task_work() to cancel all
outstanding task work requests.
