Re: [PATCH v7 1/4] spinlock: A new lockref structure for lockless update of refcount

[George Spelvin]

Just noticing that you are adding several functions that return a boolean
value as an int.  And a "gotref" local variable.

Is that just not wanting to bother with thse newfangled C99 innovations,
or do you dislike the "bool" type for some reason?

Even if it doesn't change the code in the slightest, I like to declare
things with the bool type for documentation.  I can see avoiding code
churn, but this is all new code, so I thought I'd ask.

(FWIW, stdbool.h was in gcc 3.2, which README says is the minimum
supported version, although that's probably outdated information.)
