Leandro Lupori 572e3575db aacraid: reduce max I/O size to avoid DMA issues ... Reserve one page for the DMA subsystem, that may need it when the I/O buffer is not page aligned. Without this change, writes with the maximum allowed size failed, if: - physical memory was fragmented, making it necessary to use one DMA segment for each page - the buffer to be written was not page aligned, causing the DMA subsystem to need one extra segment In the scenario above, the DMA subsystem would run out of segments, resulting in a write with no SG segments, that would fail.
