Linus Torvalds 935d8aabd4 Add file_ns_capable() helper function for open-time capability checking ...

Nothing is using it yet, but this will allow us to delay the open-time
checks to use time, without breaking the normal UNIX permission
semantics where permissions are determined by the opener (and the file
descriptor can then be passed to a different process, or the process can
drop capabilities).
