Unable to mount compressed root f/s because init_mtd() does n ot r egister block device!

[Vipin Malik]

David,
But isn't the same init calls method used to init the stuff in the
2.4.x series of kernels. So it's not just a 2.2.18/19 issue.

Thanks

Vipin
P.S. Did you look at the 2nd patch to inode-v23.c that I sent yesterday
(to fix the partial page write stuff)?

Either we stop using initcalls for the MTD stuff in 2.2.18 - just revert
to 
the old method as we did in earlier 2.2, or we fix the remainder of
2.2.19 
to use initcalls properly. Probably the former.
