Modified files: sys/compat/svr4 svr4_misc.c syscalls.master Log: Make svr4_sys_waitsys() a lot less ugly and mark it MPSAFE. - If the WNOWAIT flag isn't specified and either of WEXITED or WTRAPPED is set, then just call kern_wait() and let it do all the work. This means that this function no longer has to duplicate the work to teardown zombies that is done in kern_wait(). Instead, if the above conditions aren't true, then it uses a simpler loop to implement WNOWAIT and/or tracing for only stopped or continued processes. This function still has to duplicate code from kern_wait() for the latter two cases, but those are much simpler. - Sync the code to handle the WCONTINUED and WSTOPPED cases with the equivalent code in kern_wait(). - Fix several places that would return with the proctree lock still held. - Lock the current process to prevent lost wakeup races when blocking.
