[PATCH] 3w-9xxx: don't unmap bounce buffered commands

2015-10-03 Thread Christoph Hellwig
3w controller don't dma map small single SGL entry commands but instead bounce buffer them. Add a helper to identify these commands and don't call scsi_dma_unmap for them. Based on an earlier patch from James Bottomley. Fixes: 118c85 ("3w-9xxx: fix command completion race") Reported-by: T??th
