JFFS2 garbage collector blocking for minutes after mount

Martin, you may should try our Centralizes Summary (CS) patch. It stores
every relevant memory representation at umount time, so at mount (if the
previous unmount was a clean one) you need only to read it without any
scanning and rebuilding.

It is downloadable from our web site
(http://www.inf.u-szeged.hu/jffs2/mount.php). I recommend the variant
which stores reference information on the first erase block.
