In spite of SPLICE_F_MOVE, kernel read pages from ioerr device.
I saw messages in dmesg output even when read() calls was commented.
It is OK, I understand, that this flag is not implemented now.
1. But i don't understand why second splice() call does not return error in
that case.
2. If SPLICE_F_MOVE will be implemented, read from pipe sohuld return io error.
does not it ? it seems that this never happen by design :(
P.S.
without any flags (O_NONBLOCK,SPLICE_F_NONBLOCK,SPLICE_F_MOVE) bahviour is
exactly the same.
