From e1f19857f94be09f9526f180e64f20138bd4e394 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Wed, 7 Dec 2022 09:43:08 +0100 Subject: fs: namei: Allow follow_down() to uncover auto mounts This function is only used by NFSD to cross mount points. If a mount point is of type auto mount, follow_down() will not uncover it. Add LOOKUP_AUTOMOUNT to the lookup flags to have ->d_automount() called when NFSD walks down the mount tree.
