Message-Id: <1319821210-7374-5-git-send-email-dmonakhov@openvz.org> Date: Fri, 28 Oct 2011 21:00:07 +0400 From: Dmitry Monakhov <dmonakhov@...nvz.org> To: linux-ext4@...r.kernel.org Cc: achender@...ux.vnet.ibm.com, tytso@....edu, Dmitry Monakhov <dmonakhov@...nvz.org> Subject: [PATCH 4/7] ext4: punch_hole fix extent conversion Currently punched extent converted to uninitialized incorrectly, in fact i'm not shure whenever we actually need that conversion, but if we do that let's do it right.
