If anyone has any objections, please let me know. ------------------ From: Oleg Nesterov commit 5ba53ff648e785445a32ba39112ed07e4cf588d0 upstream. Commit 77097ae503b1 ("most of set_current_blocked() callers want SIGKILL/SIGSTOP removed from set") removed the initialization of newmask by accident, causing ltp to complain like this: ssetmask01 1 TFAIL : sgetmask() failed: TEST_ERRNO=???(0): Success Restore the proper initialization.
