I've just been told that it's not OK to call printk while holding a lock.

perhaps that is lock related to terminal?

This came as a surprise to me, as I've written thousands of lines of code
that calls printk while holding multiple locks, and have not seen any
problem. The only explanation I was given was that it can deadlock.
Is this correct? I thought there were very few places where it was not safe
to call printk.
