From 50f5fdaea9cd6941e51ea6e07d8c15265917bb86 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Wed, 7 Dec 2022 09:43:07 +0100 Subject: [PATCH] NFSD: Teach nfsd_mountpoint() auto mounts Currently nfsd_mountpoint() tests for mount points using d_mountpoint(), this works only when a mount point is already uncovered. In our case the mount point is of type auto mount and can be coverted. i.e. ->d_automount() was not called. Using d_managed() nfsd_mountpoint() can test whether a mount point is either already uncovered or can be uncovered later.
