Reducing regex makes sense.
git grep -l -E "xdp"|wc -l
348
git grep -l -E "[^a-z0-9]xdp[^a-z0-9]"|wc -l
295

The false positive match was:
+drivers/hwmon/pmbus/Kconfig
+drivers/hwmon/pmbus/Makefile
+drivers/hwmon/pmbus/xdpe12284.c
+drivers/net/ethernet/natsemi/ns83820.c
+drivers/net/ethernet/neterion/s2io.c
+drivers/net/ethernet/neterion/s2io.h
+drivers/net/ethernet/neterion/vxge/vxge-config.c
+drivers/net/ethernet/neterion/vxge/vxge-config.h
+drivers/net/ethernet/neterion/vxge/vxge-traffic.c
+drivers/net/ethernet/sis/sis900.c
+drivers/net/ethernet/sis/sis900.h
+drivers/net/wireless/ath/ath5k/ath5k.h
+drivers/net/wireless/ath/ath5k/base.c
+drivers/net/wireless/ath/ath5k/debug.c
+drivers/net/wireless/ath/ath5k/dma.c

so it's pretty much hwmon and few drivers.
I agree that sparing xdp from hwmon patches is a good thing :)
