From: Mark Fasheh Date: Mon, 18 Jun 2007 18:22:56 +0000 (-0700) Subject: ocfs2: support writing of unwritten extents X-Git-Tag: v2.6.23-rc1~781^2~6 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b27b7cbcf12a1bfff1ed68a73ddd7d11edc20daf;p=pandora-kernel.git ocfs2: support writing of unwritten extents Update the write code to detect when the user is asking to write to an unwritten extent. Like writing to a hole, we must zero the region between the write and the cluster boundaries. Most of the existing cluster zeroing logic can be re-used with some additional checks for the unwritten flag on extent records. Signed-off-by: Mark Fasheh --- Reading git-diff-tree failed
