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_struct 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.
