Suppose addr & PAGE_MASK is 2048 and len is 4096. Then= we want two pages in the array, but it looks like the loop will exit after the first iteration. I think we need to set addr &=3D ~PAGE_MASK before the lo= op, or I am missing something. I'm not sure when non-page-aligned ABD buffers can arise in practice though. --=20 You are receiving this mail because: You are the assignee for the bug.=
