ext4: init pagevec in ext4_da_block_invalidatepages
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() Reviewed-by: Lukas Czerner <lczerner@redhat.com> Reviewed-by: Carlos Maiolino <cmaiolino@redhat.com> Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: stable@vger.kernel.org
