This support allows applications to pull ring buffers from controller firmware for debugging firmware related issues. What this patch does is sends reqeust to firmware to release the buffers prior to host reset. This will allow what ever debug info is there prior to reset to be dma'd to host memory. With out this fix, some of the debug data would been lost. Signed-off-by: Eric Moore Signed-off-by: James Bottomley --- Reading git-diff-tree failed
