To be clear, this is the man page definition.  The source code defines this as:

int fi_alias(struct fid *fid, struct fid **alias_fid, uint64_t flags)

This in turn translates into fi_control().

Given that struct fid is the first element of fid_ep, the ABI should be fine.  This could change the API.

I would add fi_ep_alias over modifying fi_alias, and update the man page accordingly.
