Fix append mode and expand regress. I've added an append flag to the state but we could just as easily store the open flag instead. - todd Index: lib/libc/stdio/fmemopen.c === RCS file: /cvs/src/lib/libc/stdio/fmemopen.c,v

kqueue_scan_setup/finish

2020-08-14 Thread Martin Pieuchot
The previous change introducing the kqueue_scan_setup()/finish() API required to switch poll(2) internals to use the kqueue mechanism has been backed out. The reason for the regression is still unknown, so let's take a baby step approach. Diff below introduces the new API with only minimal
