Re: [PATCH 00/17] VFS: Filesystem information and notifications [ver #17]

If you look at the patch I posted in this thread, I think it properly
supports open_how and RESOLVE_* flags.  But remember it's opening a file
that is already present, in RO mode, no creation allowed, so most of the
open_how interactions are limited.

Something we should consider adding to openat2() at some point is the ability
to lock on open/create.  Various network filesystems support it.
