With recent discussion on the LKML[1], it seems likely that Linux will finally support posix_fadvise in a useful way with the FADV_DONTNEED flag. This should allow us to minimize the effect of rsync on the system's working set. Add the necessary wrapper to syscall.c.

V1->V2: Check to see if our current ppos is >= i_size after a short DIO read, just in case it was actually a short read and we need to just return. This is similar to what already happens in the write case. If we have a short read while doing O_DIRECT, instead of just returning, fallthrough and try to read the rest via buffered IO. BTRFS needs this because if we encounter a compressed or
