Without this patch, if /proc/self/uid_map is not exist,
the mount test case will fail and no any prompting.
After applied this patch, the case will prompt why it fail.
Just as follows:
root@kernel-host:/opt/kernel> make -C tools/testing/selftests TARGETS=mount run_tests
make: Entering directory `/opt/kernel/tools/testing/selftests'
for TARGET in mount; do \
make -C $TARGET; \
done;
make[1]: Entering directory `/opt/kernel/tools/testing/selftests/mount'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/opt/kernel/tools/testing/selftests/mount'
for TARGET in mount; do \
make -C $TARGET run_tests; \
done;
make[1]: Entering directory `/opt/kernel/tools/testing/selftests/mount'
ERROR: No /proc/self/uid_map exist
make[1]: Leaving directory `/opt/kernel/tools/testing/selftests/mount'
make: Leaving directory `/opt/kernel/tools/testing/selftests'
