Modified files: (Branch: RELENG_6)
sys/fs/fifofs fifo_vnops.c
Log:
Merge fifo_vnops.c:1.118 from HEAD to RELENG_6:
Only poll the fifo for read events if the fifo is attached to a readable
file descriptor. Otherwise, the read end of a fifo might return that it
is writable (which it isn't).
Only poll the fifo for write events if the fifo attached to a writable
file descriptor. Otherwise, the write end of a fifo might return that
it is readable (which it isn't).
In the event that a file is FREAD|FWRITE (which is allowed by POSIX, but
has undefined behavior), we poll for both.
