Content-Type: text/plain; charset=ISO-8859-2 Content-Transfer-Encoding: 7bit Sender: owner-linux-mm@kvack.org List-ID: To: linux-mm@kvack.org, LKML Hi, I've hit BUG_ON(atomic_dec_and_test(&huge_zero_refcount)) in put_huge_zero_page right now. There are some "Bad rss-counter state" before that, but those are perhaps unrelated as I saw many of them in the previous -next. But even with yesterday's next I got the BUG.
