ext4_da_block_invalidatepages is missing a pagevec_init(), which means that pvec->cold contains random garbage. This affects whether the page goes to the front or back of the LRU when ->cold makes it to free_hot_cold_page() Signed-off-by: Eric Sandeen <sandeen@redhat.com> --- -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
