Subject: [PATCH 0/6 v3] Lazy itable initialization for Ext4

Hi all,

not much has changed since my last post. Some small cleanup and adjustments
proposed by Andreas. There are two noticeable changes though:

 * you can now mount with inititable=n option, where n is a number which
   be used as wait multiplier for thread scheduling purposes (see patch #3).

 * introduced sysfs interface for advertising features like lazy itable
   initialization, to user space (see patch #6)

Thanks for review!

-Lukas
