* optimize queue->lock, use atomic operations if possible
* do we need ctask->sg_count? can we use ctask->sg instead?
* optimize HEAD + SENDBUF logic, no need to have two "if" statements:
}
ctask->r2t = r2t;
ctask->in_progress = IN_PROGRESS_SOLICIT_WRITE;
/* can goto to fixme */
}
if (ctask->in_progress == IN_PROGRESS_SOLICIT_WRITE) {
r2t = ctask->r2t;
_solicit_again:
/*
* send Data-Out's payload whitnin this R2T sequence.
*/
if (r2t->data_count) {
fixme:
len = r2t->sendbuf.size - r2t->sendbuf.sent;
if (len > r2t->data_count) {
len = r2t->data_count;
* data_xmit(): recover sendpage() error.
* make sense to split data_recv() and exctract data-in processing into
separated function. Call it from header processing context directly if
there is an iSCSI data and from data_recv() later on conn state machine
processing.
* restructure header processing code into set of small functions.
* prefetch in tcp_copy_bits().
