3.5.7.3 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Eric Sandeen <[email protected]> commit 66bea92c69477a75a5d37b9bfed5773c92a3c4b4 upstream. 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 <[email protected]> Reviewed-by: Carlos Maiolino <[email protected]> Signed-off-by: Eric Sandeen <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]> [ herton: adjust context ] Signed-off-by: Herton Ronaldo Krzesinski <[email protected]> --- fs/ext4/inode.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/fs/ext4/inode.c b/fs/ext4/inode.c index 9e9aed3..75f537f 100644 --- a/fs/ext4/inode.c +++ b/fs/ext4/inode.c @@ -1491,6 +1491,8 @@ static void ext4_da_block_invalidatepages(struct mpage_da_data *mpd) index = mpd->first_page; end = mpd->next_page - 1; + + pagevec_init(&pvec, 0); while (index <= end) { nr_pages = pagevec_lookup(&pvec, mapping, index, PAGEVEC_SIZE); if (nr_pages == 0) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
