I tested the patch and works ok now. Thanks Américo Wang !
Without it, I can reproduce the bug.

FWIW, that looks like the right fix to me.
Also CC'ing Tony Luck as he reported what appears to be the same issue
on the 25'th.

Anca reported a bug:
[15117.080119] BUG: unable to handle kernel paging request at fffffffffffffff3
[15117.080152] IP: [<ffffffff811b4989>] vma_stop+0x19/0x40
Linus did the initial analysis, and found this was caused
by commit ec6fd8a4355c ("report errors in /proc/*/*map*
sanely"), which replaces NULL with various ERR_PTR() cases.
This is true, that commit changed the return value of m_start(),
which will return an error pointer on failure, but Al forgot
to check the error pointer in m_stop() which will be called
when m_start() fails. This patches fixes it.

I did this slightly differently, and put the check in m_stop()
instead, because I felt that matched the logic of m_start, while
vma_stop() is more of an internal helper thing.
I dunno. I don't think it matters. But one thing I reacted to was that
when I was walking through the logic, I really wanted to say "seq_file
is wrong to call m_stop if m_start returned an error code". I really
felt like "hwy, if ->start fails, we damn well shouldn't have called
->stop".
But I guess we're stuck with that particular semantic for seq_files by now.

This is a good point and makes prefect sense.

Yup, I guess there are some seq_file users still rely on this behavior,
we can fix them all later.

V2: move the check into m_stop() as suggested by Linus,
also, most ->show() implementations assume the second parameter 'v'
is not NULL, this fixes them too.
Anca reported a bug:
[15117.080119] BUG: unable to handle kernel paging request at fffffffffffffff3
[15117.080152] IP: [<ffffffff811b4989>] vma_stop+0x19/0x40
Linus did the initial analysis, and found this was caused
by commit ec6fd8a4355c ("report errors in /proc/*/*map*
sanely"), which replaces NULL with various ERR_PTR() cases.
This is true, that commit changed the return value of m_start(),
which will return an error pointer on failure, but Al forgot
to check the error pointer in m_stop() which will be called
when m_start() fails. This patches fixes it.

Linus, forget this one, I saw you already checked in your own
fix, I will make one based on that. :)

I din't test the above patch.
Linus already have the fix in his tree.

Yes, I really should pull before I made a patch. :-/

In the future, we will not call ->stop() anymore when ->start() fails,
so ->start() is responsible to do cleanups within itself.
