Hello,
I have a question about device number extension in "e2fsprogs-1.35". In Linux kernel 2.6, device number is extended from 16-bit to 32-bit. All utilities and libraries should make corresponding extension for this new feature in kernel 2.6. Following operation defines type "kdev_t" as "unsigned short" type, thus
the device number has only 16-bit.
In file lib/ext2fs/jfs_user.h: 4 typedef unsigned short kdev_t; In file misc/jfs_user.h: 4 typedef unsigned short kdev_t; In file debugfs/jfs_user.h: 4 typedef unsigned short kdev_t; It seems not to correspond to device number extension.I think Kdev_t should be defined as 32-bit long int. The attached patch is for device number extension.
As following:
