SubjectRe: [PATCH] scripts/gdb: replace "is 0" by "== 0"

Usually, only for "None", "False" or "True" (but for the latest, this
doesn't usually make sense).

It would be more consistent with the other uses (like the while below
and the ifs even further). However, I don't fully understand this code
(notably the "node = node.address.cast(...)" where node is not defined
yet and node is replaced by the value of "root['rb_node']" just after),
so can't say for sure node cannot be equal to something eveluating to
False in some conditions.
Writing is easy; all you do is sit staring at the blank sheet of paper until
drops of blood form on your forehead.
