The FTL exists merely as a wrapper layer for MTD. As long as we can achieve the encapsulation from MTD to Block, there is no need to expose the FTL interface to the application. > > > > > > Ok, that makes sense. When usIng a wear levelling library like dhara the user should NOT register the MTD but just pass it to dhara_initialize() that would create the block device using register_blockdriver, correct? > > Yes, this is the correct sequence. In that case I think it would be better not to use `register_mtddriver` but instead something like `register_ftlchdriver` or `register_b*and*chdriver` to be in line with `register_blockdriver`. -- This is an automated message from the Apache Git Service.
