The list_splice_init_rcu() can be used as a stack onto which full lists are pushed, but queue-like behavior is now needed by some security policies. This requires a list_splice_tail_init_rcu(). This commit therefore supplies a list_splice_tail_init_rcu() by pulling code common it and to list_splice_init_rcu() into a new __list_splice_init_rcu() function. This new function is based on the existing list_splice_init_rcu() implementation. Signed-off-by: Petko Manolov <petkan@mip-labs.com> Cc: Mimi Zohar <zohar@linux.vnet.ibm.com> Signed-off-by: Paul E.
