Subject: Re: [PATCH -rfc 4/4] locking/rtmutex: Support spin on owner (osq)

s/CONFIG_DEBUG_RT_MUTEXES/DEBUG_RT_MUTEXES/?

Or perhaps even drop "&& !CONFIG_DEBUG_RT_MUTEXES" entirely, because
that test currently always evaluates to true, so it might not be needed.

Running 
   scripts/checkkconfigsymbols.py --diff $sha1..$sha2

helps catching typos like this.
