When you open the 138.Pa /dev/ksyms 139file, you have access to an ELF image which represents a snapshot of the state of the kernel symbol information at that instant in time. Keeping the device open does not block the loading or unloading of kernel modules. To get a new snapshot you must close and re-open the device. 140.Pp 141A process is only allowed to open the 142.Pa /dev/ksyms --- 12 unchanged lines hidden --- | 134.Sh BUGS 135Because files can be dynamically linked into the kernel at any time the symbol 136information can vary.
