specific function _cancel_timer as besides deactivating
a timer, it also ensures that the timer is stopped on all

Staging: lustre: Iterate list using list_for_each_entry
Code using doubly linked list is iterated generally using list_empty and
list_entry functions, but it can be better written using list_for_each_entry
macro.
This patch replaces the while loop containing list_empty and list_entry with
list_for_each_entry and list_for_each_entry_safe. list_for_each_entry is a
macro which is used to iterate over a list of given type. So while loop used to
iterate over a list can be replaced with list_for_each_entry macro. However, if
list_del is used in the loop, then list_for_each_entry_safe is a better choice.
This transformation is done by using the following coccinelle script.
