While running selftests binderfs_test on stable rc 5.4 and 5.5 branches the following warning on arm64, arm, x86_64 and i386.

This warning was noticed on Linus's tree and reported [1] and then Christian Brauner investigated this problem.

I've sent a fix (You should've been Cced on.) which has made it into Greg's tree so should land in mainline soon. I've also made sure to Cc stable meaning it should land in all relevant kernels soon after. Please see: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git/commit/...

Thanks! Christian
