With follow_automount now overriding creds -uid that we export to userspace changes and that breaks existing -setups. - -To remove the regression set wq_uid and wq_gid from -current_real_cred()->uid and current_real_cred()->gid respectively. -This restores the current behavior as current->real_cred is identical -to current->cred except when override creds are used. - -Cc: stable@vger.kernel.org -Fixes: aeaa4a79ff6a ("fs: Call d_automount with the filesystems creds") -Reported-by: Seth Forshee <seth.forshee@canonical.com> -Tested-by: Seth Forshee <seth.forshee@canonical.com> -Signed-off-by: "Eric W.
