I haven't tested on much in the way of older kernels, but I wouldn't
expect it to cause any problems. The only behavior change that should
be introduced is the F_GETLK test, and older kernels should pass that
just fine (modulo v3.15 which has a regression that should be patched
soon). The rest of the changes are just cleanups, and shouldn't
introduce any behavioral changes.
