From: David Woodhouse Date: Tue, 5 Aug 2008 17:08:56 +0000 (+0100) Subject: Support 'discard sectors' operation. X-Git-Tag: v2.6.28-rc1~733^2~122 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fdc53971bce56d299cb5f1f06ecbff30b34cbaf2;p=pandora-kernel.git Support 'discard sectors' operation. We can benefit from knowing that the file system no longer cares about the contents of certain sectors, by throwing them away immediately and then never having to garbage collect them, and using the extra free space to make our operations more efficient. Do so. Signed-off-by: David Woodhouse Signed-off-by: Jens Axboe --- Reading git-diff-tree failed
