And here I thought we had a fairly strong rule that we should not merge unused code :/
In any case, whomever wrote that function had better first explain why its not broken.
And I'm not too keen on making mutex_lock_nested() an inline due it being too easy to generate code with it. I'd much rather work around the occasional warning than have to deal with silent but unintended code spills.
