It is. Generally I think we should prefer to do the right thing rather
than adhering to the old API out of some principle.

Evaluate the impact on out-of-tree kernel patches (especially vendor
kernels) and if it is unacceptable then reject the change or augment the API
rather than changing it.

OK, we're on to a specific case. Albeit a very small one.

I think Trond's direct IO change was right. The impact on out-of-tree code
is infinitesimal. Stick a #define O_DIRECT_NEEDS_A_FILP in the header and
let the XFS guys write a four-line patch. There's no point in mucking up
the kernel API to save such a small amount of work.

Or merge XFS.
