Hello,

I have some questions about device number extension.

In Linux kernel 2.6, device number will be extended from 16-bit to 32-bit. All utilities and libraries should make corresponding extension for this new feature in kernel 2.6. 

 As following, "major" should be 12-bit, and "minor" should be 20-bit.   mmmm mmmm mmmm MMMM MMMM MMMM mmmm mmmm
But I find that “kudzu-1.1.36-1” uses structure dev_t and the operation in file pcmcia.c: 385

       dev = (pcmcia_major<<8) + sock 

If sock is greater than 256, it may has problem. So I suggest useing  macro makedev (in <include/sys/sysmacros.h>) to create device number.


Since I didn’t find any information about this aspect in homepage of this package, I wonder whether the latest version has completed the device number extension? If not, will it be completed in the future? And when?

Looking forward to answering.
