Linux device number bug report

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.

I find that “bash-2.05b-29” uses structure dev_t and operates the device number
as 16-bit.

In file examples/loadables/finfo.c: 251

       printf("Device (major/minor): %d (%d/%d)\n", (int) (st->st_dev & 0xFF),

                                               (int) major (st->st_dev),

                                               (int) minor (st->st_dev));

The device number st->st-dev should be 32-bit. But this operation only prints its lower 16-bit and it seems not to correspond to device number extension.

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.
