Re: Show module version sysfs file for built-in modules?

what about this ?
neoware:/sys/module/8139too # cat /sys/module/8139too/version
0.9.28
neoware:/sys/module/8139too # modinfo 8139too |grep "^version:"
version: 0.9.28
the latter should work completely without consulting the kernel for that information.
