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 the format of extended device number is as following: mmmm mmmm mmmm MMMM MMMM MMMM mmmm mmmm, that "major" should be 12-bit, and "minor" should be 20-bit. "M" means major device number. "m" means minor device number.

But I find that 隆掳krb5-1.2.7隆卤 uses structure dev_t and operates the
minor device number as
8-bit.
In
file krb5-1.2.7/src/util/pty/getpty.c:
109
ptynum = (int)(stb.st_rdev&0xFF)
So
it seems not to correspond to device number extension.
Since I didn隆炉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.
