Date: Wed, 29 Apr 2009 16:43:30 +0530 From: "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com> To: cmm@...ibm.com, tytso@....edu, sandeen@...hat.com Cc: linux-ext4@...r.kernel.org, "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com> Subject: [PATCH 1/2 for 2.6.31] ext4: Use -1 as the fake block number for delayed new buffer_head Block number '0' should not be used as the fake block number for the delayed new buffer. This will result in vfs calling umap_underlying_metadata for block number '0'. So use -1 instead.
