The coccinelle report
./tools/testing/selftests/move_mount_set_group/move_mount_set_group_test.c:225:18-23:
WARNING: conversion to bool not needed here
Relational and logical operators evaluate to bool,
explicit conversion is overly verbose and unneeded.

Applied. In the future use selftests/<test>: .... convention for
patch summary. Review "git log <filename>" history for how to
write summaries and change logs.

I fixed this one for now.
