<DIV>Hello,<BR><BR>I have a question about device number extension in
"e2fsprogs-1.35".<BR><BR>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. </DIV>
<DIV>
<DIV> </DIV>
<DIV>Following operation defines type "kdev_t" as "unsigned short" type, thus
the device number has only 16-bit.<BR>In file lib/ext2fs/jfs_user.h:
4<BR> typedef unsigned short kdev_t;
<BR>In file misc/jfs_user.h: 4<BR>
typedef unsigned short kdev_t; <BR>In file debugfs/jfs_user.h:
4<BR> typedef unsigned short kdev_t;
<BR>It seems not to correspond to device number extension.I think Kdev_t should
be defined as 32-bit long int.</DIV>
<DIV> </DIV>
<DIV>The attached patch is for device number extension.</DIV>
<DIV>As following:</DIV>
