Subject: [iput] BUG: Bad page state in process rm pfn:0b0ce

Greetings,

I got the below dmesg in linux-next and the first bad commit is

commit eeb9bfc39ed70ee5c389d6c9be555588e1284e62
Author: Mel Gorman <mgorman@...e.de>

    mm: remove lru parameter from __lru_cache_add and lru_cache_add_lru
    
    Similar to __pagevec_lru_add, this patch removes the LRU parameter from
    __lru_cache_add and lru_cache_add_lru as the caller does not control the
    exact LRU the page gets added to.  lru_cache_add_lru gets renamed to
    lru_cache_add the name is silly without the lru parameter.  With the
    parameter removed, it is required that the caller indicate if they want
    the page added to the active or inactive list by setting or clearing
    PageActive respectively.
