Modified files:
sys/kern uipc_cow.c
Log:
Remove some unnecessary actions by the zero-copy setup and teardown code.
Remove an incorrect comment. (Incrementing an object's reference count
does not prevent a process from exiting. The real concern here is that the
physical page must not be deleted until transmission is complete. That is
already handled by the VM system and sf_buf_free().)
