The problem exists whenever len is a multiple of the page size, so I don't = see why it should always be a linear buffer. But indeed, I'd expect I/O to a device with ashift=3D12 to always be page aligned. > But still, just in case, what would you say about this patch: Looks right to me, thanks. --=20 You are receiving this mail because: You are the assignee for the bug.=
