Subject: list: introduce list_next_entry() and list_prev_entry()
From: Oleg Nesterov <oleg@xxxxxxxxxx>
[ Upstream commit 008208c6b26f21c2648c250a09c55e737c02c5f8 ]
Add two trivial helpers list_next_entry() and list_prev_entry(), they
can have a lot of users including list.h itself. In fact the 1st one is
already defined in events/core.c and bnx2x_sp.c, so the patch simply
moves the definition to list.h.
