is useless for threaded programs, multiple threads can not share same stack. The alternative signal stack is private for thread, no lock is needed, the orignal P_ALTSTACK is now moved into td_pflags and renamed to TDP_ALTSTACK. For single thread or Linux clone() based threaded program, there is no semantic changed, because those programs only have one kernel thread in every process. Reviewed by: deischen, dfr |
