 	src/sys/kern: sys_pipe.c
 
 Log Message:
 pipe(2): Simplify PIPE_RESTART handling.
 
 Now that it applies to each side independently, we can just make it
 final, because new I/O operations are not allowed on an file that has
 had its .fo_restart called.  Makes reasoning about all this easier.
 
 XXX Consider renaming PIPE_RESTART to PIPE_CLOSING: the .fo_restart
 operation means the file is irreversibly destined to be closed soon
 and just needs any pending I/O on it to be interrupted and fail
 promptly so we can finally close the file.
