Message-Id: <1202985052-15694-2-git-send-email-aneesh.kumar@linux.vnet.ibm.com> Date: Thu, 14 Feb 2008 16:00:52 +0530 From: "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com> To: tytso@....edu, cmm@...ibm.com Cc: linux-ext4@...r.kernel.org, "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com> Subject: [RFC/PATCH] ext4: Request for journal write access early. In ext4_ext_convert_to_initialized before we need to request for journal write access before we even modify the extent length.
