One other thing: why O_CANLINK (suggested flag to open) instead of O_NOLINK?
It seems to me that for the vast majority of open()calls, you don't care whether the open fd can be flink()ed to, because you don't pass the file descriptor to an untrusted process.
A bit set to eliminate that capability is the new feature one might need for security reasons with an implemented flink() call available to programmers.
Seems like leaving "can be linked to" as the default setting and having an explicit flag to prevent that would be more efficient.
