3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Eric Sandeen <sand...@redhat.com> 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 <lczer...@redhat.com> Reviewed-by: Carlos Maiolino <cmaiol...@redhat.com> Signed-off-by: Eric Sandeen <sand...@redhat.com> Signed-off-by: "Theodore Ts'o" <ty...@mit.edu> Signed-off-by: CAI Qian <caiq...@redhat.com> Signed-off-by: Greg Kroah-Hartman <gre...@linuxfoundation.org> --- fs/ext4/inode.c | 2 ++ 1 file changed, 2 insertions(+) --- a/fs/ext4/inode.c +++ b/fs/ext4/inode.c @@ -2199,6 +2199,8 @@ static void ext4_da_block_invalidatepage 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) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
