Hi,
While checking somethings for a next release of kmod I noticed this
strange thing:
cat /sys/module/acpi_cpufreq/refcnt
18446744073709551614
We outputs this as "-1" in lsmod because we treat the value as signed.
I was just going to change it to unsigned to make it compatible with
what module-init-tools does but... For me it looks like a bug in the
kernel since in this file we just have the output of
kernel/module.c:module_refcount()
I have this behavior on 3.9.2 but judging by the missing commits in
kernel/module.c, this would also happen in latest head. I've never
seen such a value so I guess it might be difficult to reproduce it
again.
Any hints on what could cause decs to be greater than incs in module_refcount()?
