> That sounds like a bug in mutex_trylock() to me.

I disagree, I have yet to see a legitimate case where doing a trylock
on a mutex lock didn't turn out to be a bug when performed in an
atomic context.

This is particularly true in the networking, the bonding driver
has provided some excellent examples over the years :-)
