https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203366 --- Comment #8 from Jan Kokemüller <jan.kokemueller@gmail.com> --- NetBSD does something similar, but in addition they trigger the wakeup on some other condition (flag PIPE_SIGNALR): https://github.com/NetBSD/src/blob/7c38ee86e0812f49fe3889bfc1c59757688d8d16/sys/kern/sys_pipe.c#L622 This flag is set for example if this is the first read(2) after a write(2). I'm not quite sure yet why this is needed, though. -- You are receiving this mail because: You are the assignee for the bug.help
