From 9b1d0998d24f9c207d5fbdd0b8bac07284e0eda7 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 3 Mar 2010 16:19:32 -0500 Subject: [PATCH] ext4: Release page references acquired in ext4_da_block_invalidatepages We forget to release page references we acquire in ext4_da_block_invalidatepages. Luckily, this function gets called only if we are not able to allocate blocks for delay-allocated data so that function should better never be called. Also cleanup handling of index variable.
