The changes correct some comments, stop open coding mutex_lock_killable, and move the point_of_no_return variable up to when the point_of_no_return actually occurs. I don't think there is anything controversial in there but if you see something please let me know. Eric W. Biederman (6): exec: Move the comment from above de_thread to above unshare_sighand exec: Fix spelling of search_binary_handler in a comment exec: Stop open coding mutex_lock_killable of cred_guard_mutex exec: Run sync_mm_rss before taking exec_update_mutex exec: Move handling of the point of no return to the top level exec: Set the point of no return sooner fs/exec.c | 51 +++++++++++++++++++++++++++------------------------ kernel/ptrace.c | 4 ++-- 2 files changed, 29 insertions(+), 26 deletions(-)
