In the driver block.c there is this line:
do {
struct mmc_command cmd;
u32 readcmd, writecmd, status = 0;
memset(&brq, 0, sizeof(struct mmc_blk_request));
brq.mrq.cmd = &brq.cmd;
brq.mrq.data = &brq.data;
// THIS LINE
brq.cmd.arg = blk_rq_pos(req);
I saw the sector number is a 64 bit number, so can the sector be
considered a 'unique number', kind of like a unique address?
I don't see block.c actually using an address to set up a queue request
read/write; rather, just sector, block size, command, and # of sectors.
That is why I was wondering.
Thanks for the help and insight.
