(utrace_attach_task): Ditto. (finish_callback): Remove call to might_sleep(), since tracepoint handlers (and now utrace handlers) can't sleep. commit 54e7e8f0122569091f780fc0f1acc1520b09f1c4 Author: David Smith Date: Thu Oct 27 11:06:14 2011 -0500 More PR13083 fixes to avoid sleeping in the task_finder (ported). * runtime/task_finder2.c (__stp_get_mm_path): Call down_read_trylock() instead of down_read() to avoid the possibility of sleeping. (stap_start_task_finder): Call task_lock() to make sure a task's mm doesn't go away while we're looking at it. commit 6ca28847b794e03744b3fc425a5f3e07d49154b4 Merge: 40b8ed4 93ee09d Author: David Smith Date: Thu Oct 27 10:27:24 2011 -0500 Merge branch 'master' of /es/scratch/dsmith/systemtap/src into dsmith/task_finder2 ----------------------------------------------------------------------- Summary of changes: elaborate.cxx | 4 +- runtime/addr-map.c | 6 ++-- runtime/print.c | 6 ++-- runtime/runtime.h | 25 ++++++++++------- runtime/staprun/staprun.c | 53 +++++++++++++++++++----------------- runtime/stp_utrace.c | 13 +++----- runtime/task_finder.c | 30 +++++++++++++------- runtime/task_finder2.c | 26 ++++++++++++----- runtime/transport/control.c | 14 +++++++++ runtime/transport/transport.c | 21 +++++--------- runtime/transport/transport.h | 1 - runtime/transport/transport_msgs.h | 9 ++++++ translate.cxx | 17 ++++++++++- 13 files changed, 139 insertions(+), 86 deletions(-) hooks/post-receive -- systemtap: system-wide probe/trace tool
