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 +IBw-jfsutils-1.1.4+IB0- uses dev+AF8-t and operates the device number as
16-bit.
In file libfs/devices.h: 53
static inline int32+AF8-t dev+AF8-to+AF8-kdev(dev+AF8-t rdev)
+AHs-
return (major(rdev) +ADwAPA- 8 +AHw- minor(rdev))+ADs-
+AH0-
The minor device number should be 20-bit. But this operation considers minor has only
8-bit and it seems not to correspond to device number extension.
Since I didn+IBk-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.
