[PATCH v2 2/2] selftests/lkdtm: Add UBSAN config

From: Muhammad Usama Anjum
Date: Fri Jan 21 2022 - 09:52:37 EST


UBSAN_BOUNDS and UBSAN_TRAP depend on UBSAN config option.
merge_config.sh script generates following warnings if parent config
doesn't have UBSAN config already enabled and UBSAN_BOUNDS/UBSAN_TRAP
config options don't get added to the parent config.

Value requested for CONFIG_UBSAN_BOUNDS not in final .config
Requested value: CONFIG_UBSAN_BOUNDS=y
Actual value:

Value requested for CONFIG_UBSAN_TRAP not in final .config
Requested value: CONFIG_UBSAN_TRAP=y
Actual value:

Fix this by including UBSAN config.
