Well, the readpage error should be rare (and for the _normal_ case we just
do the "wait_on_page_locked()" thing). And I think we should lock the page
in order to do the truncation check, no?

But I don't have any really strong feelings. I'm certainly ok with the

Signed-off-by: Linus Torvalds <>

if you want to send it off to Andrew (or if Andrew wants to just take it

Btw, how did you even notice this? Just by reading the source, or because
you actually saw multiple errors reported?
