ARGUMENTS

12       pos
13           the loop cursor used in the list_for_each_entry_safe loop
14

DESCRIPTION

22       list_safe_reset_next is not safe to use in general if the list may be
23       modified concurrently (eg. the lock is dropped in the loop body). An
24       exception to this is if the cursor element (pos) is pinned in the list,
25       and list_safe_reset_next is called after re-taking the lock and before
26       completing the current iteration of the loop body.
