[PULL,5/8] 9pfs: drop fid_to_qid()

Commit Message

Christian Schoenebeck July 5, 2021, 11:13 a.m. UTC

There is only one user of fid_to_qid() which is v9fs_walk(). Let's
open-code fid_to_qid() directly within v9fs_walk(), because
fid_to_qid() hides the POSIX stat buffer which we are going to need
in the subsequent patch.
