Commit 0aaa8977ac ("configs: introduce debug.config for CI-like setup")
added CONFIG_PROVE_RCU_LIST=y to the common CI config,
but RCU_EXPERT is not set, and it's a dependency for
CONFIG_PROVE_RCU_LIST=y. Make sure CIs take advantage
of CONFIG_PROVE_RCU_LIST=y, recent fixes in networking
indicate that it does catch bugs.

# Help: Debugging for CI systems and finding regressions
|
|
#
|
|
# The config is based on running daily CI for enterprise Linux distros to
|
|
# seek regressions on linux-next builds on different bare-metal and virtual
|
|
# platforms. It can be used for example,
|
|
#
|
|
# $ make ARCH=arm64 defconfig debug.config
|
|
#
|
|
# Keep alphabetically sorted inside each section.
|
|
#
