While staring at some DRM_MODESET_LOCK_ALL_{BEGIN,END}() conversions
I decided I don't really like what those macros do.
The main problems that I see:
- the magic goto inside limits their usefulness to baically
a single statement, unless you're willing to look inside and
find out the name of the magic label
- can't help at all in the "we don't want to lock everything"
cases, which are quite numerous
- not at all obvious that there's a loop in there
So I figured I'd try to come up with something more universally useful.
