Change Details

``` EVFILT_SIGNAL: do not use target process pointer on detach It is enough to know knlist to remove from it, and the list is autodestroyed on last removal. PR: 275286 ``` ``` Revert "kqueue: on process exit, force-clear its registered signal events" This reverts commit 393ac29f0b8be068c8e46f76c2eeee07d20ea4df. A different fix is following, which preserves semantic, required by the sys.kqueue.proc3_test.proc3 test. ```

``` EVFILT_TIMER: intialize stop timer list in type-stable proc init, instead of fork Since kqueue timer may exist after the process that created it exited (same scenario with rfork(2) as in PR 275286), make the tailq p_kqtim_stop accessed by filt_timerdetach() type-stable. ``` ``` EVFILT_SIGNAL: do not use target process pointer on detach It is enough to know knlist to remove from it, and the list is autodestroyed on last removal.
