this is the second report in the last week which makes not a lot of sense. And this oneis makes absolutely no sense at all.
This commit affects request_irq() and the related variants and has exactly ZERO influence on anything related to that test case simply because.
I seriously have to ask the question whether this test infrastructure is actually measuring what it claims to measure.
As this commit clearly _cannot_ have the 'measured' side effect, this points to some serious issue in the tests or the test infrastructure itself.
Thanks,
tglx
