BTW, for "an open file descripter", do you mean "olddirfd" ? Because
"olddirfd" is a dir's open file descripter, how is that possible it
can become linked again ?
Yes, I mean olddirfd, and the manual says: "If oldpath is an empty
string, create a link to the file referenced by olddirfd".
Yeah, in this case will it allow to be a regular file's file descriptor.
And in the mannual page:
"This will generally not work if the file has a link count of zero
(files created with O_TMPFILE and without O_EXCL are an exception)."
I haven't gone through the code yet. Is that means we won't allow the
linkat() if the inode->i_count is zero ?
Thanks
