2008-02-21 Thread Aneesh Kumar K.V
This patch had very minimal testing. I am sending this to get the feedback on the approach. The skip_index section in the below patch is ugly. Any suggestion to improve ? NOTE: ext4_ext_convert_to_initialized error path have some BUGs. It doesn't reset the extent information in case of error. But
