kbuild: ignore cache modifiers for generating the tags files
Uwe Kleine-König [Tue, 8 Jan 2008 14:16:24 +0000 (15:16 +0100)]
With this patch I'm able to find the definition of _xmit_lock defined in
include/linux/netdevice.h as follows:

struct net_device {
...
spinlock_t _xmit_lock ____cacheline_aligned_in_smp;
}

Otherwise this counts as definition of ____cacheline_aligned_in_smp.
