Also added some code from __stp_utrace_task_finder_target_syscall_exit() that locks the 'mmap_sem' semaphore. This avoids holding the semaphore while the mmap callbacks are made. (__stp_utrace_task_finder_target_syscall_exit): Just calls __stp_call_mmap_callbacks_with_addr() in the mmap case. ----------------------------------------------------------------------- Summary of changes: runtime/task_finder.c | 132 ++++++++++++++++++++++++++++--------------------- 1 files changed, 75 insertions(+), 57 deletions(-) hooks/post-receive -- systemtap: system-wide probe/trace tool
