Subject: [PATCH] include: Silence gcc warning in linux_list.h
Compiler complained about empty prefetch() macro:
| ../include/linux_list.h:385:66: warning: right-hand operand of comma expression has no effect [-Wunused-value]
| 385 | for (pos = list_entry((head)->next, typeof(*pos), member), \
| | ^
Use nftables' variant instead which gcc seems to like more.
Fixes: 36d2ed3de20a3 ("major cleanup of index2name infrastructure: use linux list (and fix leak in the nlif_close path)")
Signed-off-by: Phil Sutter <phil@nwl.cc>
(cherry picked from commit 90ba6791824ef761f9f397c05b20a2f102dbe74a)
