Re: Path Name to kdev_t

[Irfan Hamid]

in all functions of the driver where you will need the kdev_t (e.g.: the VFS 
layer hooks) you will receive either a struct inode* and/or the struct file* 
of the device file. the i_rdev member of struct inode is defined as the 
kdev_t of the particular device.

hope this helps.

regards,
irfan.
