Can you call F_REOPEN multiple times, or only once after
open(O_DEFEROPEN)?
If F_REOPEN should support multiple calls, then we need a filp specific
callback:
The FIFO code must send wake-ups when a filp is promoted from O_RDONLY
to O_RDWR, and it doesn't support O_NONE (fifo_open fails, potential
races in pipe_poll).
