Subject: Re: [PATCH] uninitialized groups ported - kernel

Kernel build was failing with the uninitialized patches when 
CONFIG_CRC16=m. The patch below resolves this issue.

Also, when testing the patches, filesystem mount fails:

EXT4-fs error (device sdc1): ext4_check_descriptors: Checksum for group 1 failed (0!=1)

EXT4-fs: group descriptors corrupted!

EXT4-fs error (device sdc1): ext4_check_descriptors: Checksum for group 7 failed (0!=1)

Even though the uninitgrps feature is not enabled, the gdp->bg_checksum 
on disk is nonzero.
Mingming will pull the patches out of the patch queue until this is fixed.

Thanks
Avantika
