Hello Ferenc,

I doubt that actual CRC checking takes so much time. It is mainly *read*
operation.

Because what your option does is

+#ifdef CONFIG_JFFS2_SUMMARY_NOCRCCHECK	
+	ic->state = INO_STATE_CHECKEDABSENT;
+#endif

which is incorrect. You should not skip the checking process for inodes.
When I proposed not to check CRCs I meant another thing. And now I'm
uncertain that what I proposed is absolutely correct.

Please, bear in mind that the primary goal of the checking process is
not to check CRCs but rather to detect which nodes are valid, which are
obsolete. This is done by building fake fragtrees.

Correct me if I'm wrong.
