Now with fallocate and discard support upstream, are you planning to
increment the glusterfs-api version ? I still see the version as 4 in
the git master. I need to decide if I should use version 4 or 5 to
determine the availability of discard support from QEMU.

This is yet to be determined. The fallocate/discard introduces change in the internal protocol/rpc and we're figuring out the right time to bring this patch into a release branch. Since release-3.4 is still "unreleased" there is a possibility, but we have not yet decided on it.
