Hi all,
after the recent introduction of dma_buf_prepare we stopped honoring
IDE_DMA_BUF_SECTORS (the guest can issue dma requests with a greater
total length than IDE_DMA_BUF_SECTORS).
This patch adds the IDE_DMA_BUF_SECTORS limit back in place.
Comments are welcome.
Aren't 64K sector requests legal?
Looking at ide_cmd_lba48_transform().
I am not sure about that, but I would think not since we define
MAX_MULT_SECTORS 16
If I change MAX_MULT_SECTORS, am I supposed to see smaller dma requests?
