Subject: [PATCH] [RESEND] ext4: Release page references acquired in ext4_da_block_invalidatepages
Date: Wed,  3 Mar 2010 14:54:07 +0100	[thread overview]
Message-ID: <1267624447-19923-1-git-send-email-jack@suse.cz> (raw)

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.
