I= t is enough to manually print the submaps from kgdb, and perhaps to look at the = kmem sizing. Surplus would be to run a stress test to see how much threads can = be created on unpatched vs. patched kernel. I do not want to become a target for accusation of breaking [*] smaller arc= hes. * Breaking there has very subtle meaning since I do not expect that the boo= t to singlemode would be broken, but I would be not surprised and even expect th= at some loads that worked before the change, start breaking after it, sometime= s in non-obvious ways. --=20 You are receiving this mail because: You are the assignee for the bug.=
