In this sentence, "generally" probably means "typically", so it
depends on the specific file system's behavior. I don't know the
CephFS behavior in this case. However, at least files created with
O_TMPFILE are an exception. Does CephFS support creating files with
O_TMPFILE? Such files can (and often will) go from the unlinked and
open state to the linked and closed state.
Hmm, yeah. I didn't see anywhere is disallowing to create with
O_TMPFILE. Let me have a look at this case carefully later.
Thanks very much for your reporting Sebastian.
