H A Dballoc.cdiff 2ccb5fb9f113dae969d1ae9b6c10e80fa34f8cd3 Tue Jan 06 03:49:55 CET 2009 Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> ext4: Use new buffer_head flag to check uninit group bitmaps initialization

For uninit block group, the on-disk bitmap is not initialized. That
implies we cannot depend on the uptodate flag on the bitmap
buffer_head to find bitmap validity. Use a new buffer_head flag which
would be set after we properly initialize the bitmap. This also
prevents (re-)initializing the uninit group bitmap every time we call
ext4_read_block_bitmap().
