No it can't - we hold an additional ref on the page, so reclaim will back off. Still, it feels a bit flakey.
And we're not supposed to take lock_page() inside journal_start, because that's a ranking violation. Probably i_sem will prevent an actual deadlock occurring, however. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
