This is a very early prototype of what i working on. I have done only minimal testing of this. To use one need to use the below steps. io_manager io_mng = stack_io_manager_init(); stack_push_io_manager(io_mng, unix_io_manager); stack_push_io_manager(io_mng, undo_io_manager); flags = EXT2_FLAG_SOFTSUPP_FEATURES | EXT2_FLAG_RW; retval = ext2fs_open2(dev_name,"tdbfilename=/tmp/test.tdb&", flags, superblock, block_size, io_mng, ¤t_fs); I am sending this across to find out if this is the approach that we want to follow. -aneesh - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
