commit 7fc97c102a7c58e4d25eb6527ae8a1c536e12f1c
Author: David Smith <dsmith@redhat.com>
Date: Thu Oct 13 12:37:29 2011 -0500
Fixed PR13083 by no longer calling mmput() when possible.
* runtime/task_finder.c (__stp_utrace_attach): Don't call
get_task_mm()/mmput(). Since we're in the context of that task, the mm
should stick around (and mmput() can sleep).
(__stp_call_mmap_callbacks_with_addr): Ditto.
(__stp_utrace_attach_match_tsk): Ditto.
(__stp_call_mmap_callbacks_for_task): Ditto.
