I was unable to repro= duce the problem but I think what's happening is that an array for receiving a b= ulk allocation is partially populated and the bulk allocator is returning witho= ut allocating at least one page. Allocating even one page should hit the path where kswapd is woken. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
