Subject: bounce_sg and sg in mmc_queue
Date: Wed, 21 Sep 2011 11:26:54 -0700 [thread overview]
Message-ID: <4E7A2C6E.70408@linux.intel.com> (raw)
Hello:
Could anyone tell me in struct mmc_queue, what is the difference between
'struct scatterlist *bounce_sg' and 'struct scatterlist *sg' is?
I see 'bounce_sg' get used to copy data from/to the buffer upon a host
read/write operation so I assume 'bounce_sg' points to the most recent
data from a host controller read/write operation.
Thanks for the help.
