sys/kern : sys_generic.c sys_pipe.c
Log message:
Don't return EPIPE from pipe kqfilter
Proceed with the registration of an EVFILT_WRITE filter even if the
pipe's other end has been closed, instead of failing with error EPIPE.
The filter will trigger immediately. This reduces the possible outcomes
when a kevent(2) call and a close(2) call race on the different ends
of a pipe.
This fixes a failure of lang/ghc unit test as reported by gnezdo@.
OK gnezdo@ mpi@
