LIST_SAFE_RESET_NEXT(9)                     Data Types                    LIST_SAFE_RESET_NEXT(9)



NAME
       list_safe_reset_next - reset a stale list_for_each_entry_safe loop

SYNOPSIS
       list_safe_reset_next(pos, n, member);

ARGUMENTS
       pos
           the loop cursor used in the list_for_each_entry_safe loop

       n
           temporary storage used in list_for_each_entry_safe

       member
           the name of the list_head within the struct.

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