Yeah, that looks about right to me.
You should probably use kmap_local_page() rather than kmap_atomic()
these days, but other than that this looks fairly straightforward, and
I much prefer the model where we very much force that "must be the
first iovec entry".
As you say, maybe not shorter, but a lot more straightforward.
That said, looking through the patch series, I see at least one other
issue. Look at parisc:
+#define O_ALLOW_ENCODED 100000000
yeah, that's completely wrong. I see how it happened, but that's _really_ wrong.
I would want others to take a look in case there's something else. I'm
not qualified to comment about (nor do I deeply care) about the btrfs
parts, but the generic interface parts should most definitely get more
attention.
By Al, if possible, but other fs people too..
