Remind me why we > don't just open-code the atomic_add_unless in batman-adv. Because some developers behind batman-adv and fault_inject thought that it is easier readable and David S. Miller said that it is a good idea to have something like it in atomic*.h Other places were it can be used: * drivers/media/video/omap3isp/ispstat.c * drivers/s390/net/qeth_core_main.c * fs/ext4/ext4.h * fs/xfs/linux-2.6/xfs_buf.c * mm/memcontrol.c * net/core/drop_monitor.c * net/phonet/pep.c > Since people apparently think that this patch is a good idea, I'll merge it > in the asm-generic tree once I understand why this is done. Don't feel pushed --- you can just say that you absolutely doesn't want it. I only tried to keep David happy, but don't want to start a fight over it. thanks, Sven
