Re: Have RESOLVE_* flags superseded AT_* flags for new syscalls?

Will there be any new flags for openat in the future?  If not, we can
just use a constant mask in an openat2-based implementation of openat.

One thing we might want to look at is implementing support for
lock-on-open/create and sharing modes in openat2().  Various network
filesystems support this.  Wine, CIFS and Samba particularly might be
interested in this.

But will those be O_ flags that need to be passed to openat?

Ignoring locking requests on older kernels because of the openat flag
handling seems problematic.

Thanks,
