It seems that the patch is rejected in patchwork,
Could any one tell me the reason?
I had nack'd it because I was worried at the time about the super crc
errors that Dave had found in the past. Sorry, I really thought I had
sent email about it.
But Dave has a great point in his reply about validating the super
generation.
Thanks for the reason.
I'll search and look at Dave's mail and dig into it.
Although as mentioned in the reply to David,
the main problem is that I found two disk images with crazy values in
superblock and wrong csum,
but generation is still 4, and ignoring the csum error caused kernel BUG.
Thanks,
Qu
