Subject: [uml-devel] What's wrong with tmpfs?
Date: Sun, 30 Oct 2005 06:24:38 -0600 [thread overview]
Message-ID: <200510300624.38794.rob@landley.net> (raw)
Under User Mode Linux in 2.6.14, would someone please explain to me why this
test:
static int graft_tree(struct vfsmount *mnt, struct nameidata *nd)
{
int err;
if (mnt->mnt_sb->s_flags & MS_NOUSER)
return -EINVAL;
Is triggering when I try to mount tmpfs? Is this happening for anybody else?
Shouldn't I be getting a fresh superblock or something? (Is this just a User
Mode Linux issue? Haven't got a spare box set up to boot it on real hardware
just yet...)
If somebody needs a reproduction sequence, I'm happy to oblige. In theory
"mount -t tmpfs /mnt /mnt" should do it, but if it was _that_ simple it
wouldn't have shipped...
Rob
