Description
In the Linux kernel, the following vulnerability has been resolved:
rv: Fully convert enabled_monitors to use list_head as iterator
The callbacks in enabled_monitors_seq_ops are inconsistent. Some treat the
iterator as struct rv_monitor *, while others treat the iterator as struct
list_head *.
This causes a wrong type cast and crashes the system as reported by Nathan.
Convert everything to use struct list_head * as iterator. This also makes
enabled_monitors consistent with available_monitors.
