When reviewing Clang Static Analyzer reports against a branch that had
experimental header changes based on the Coverity model file to inform
it that KM_SLEEP allocations cannot return NULL, I found a report saying
that a KM_PUSHPAGE allocation returned NULL. The actual implementation
does not return NULL unless KM_NOSLEEP has been passed, so we backport
the correction from the experimental header changes to the Coverity
model.
