We've again got this use of spinlocks here but no IRQ safety - what
exactly is going on with the locking? In general all of the locking in
this stuff is raising very serious alarm bells with me, I don't
understand what is being protected against what and there's some very
obvious bugs. We could probably use some documentation about what the
locking is supposed to be doing.
I agree, there are locking issues here, Am revisiting them all before I
send a next version.

This indentation is confusing.
I agree, will fix such instances in next version.
