Hi vabank,

Thanks for your reply.

I have already tested that api open_by_devnum.
But it oops.

The problem is open_by_devnum(block_device *bd, int mode)
calls blkdev_get function which makes use of bd->bd_inode field to get the block device structure.

How I can get the inode field for a dev_t structure?

Sorry for the inconvenience.

Regards,
Explorer.
