From 97d3ac75e5e0ebf7ca38ae74cebd201c09b97ab2 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 24 Apr 2011 19:06:16 +0000 Subject: xfs: exact busy extent tracking Update the extent tree in case we have to reuse a busy extent, so that it always is kept uptodate. This is done by replacing the busy list searches with a new xfs_alloc_busy_reuse helper, which updates the busy extent tree in case of a reuse. This allows us to allow reusing metadata extents unconditionally, and thus avoid log forces especially for allocation btree blocks.
