ACK. I'll rebase commit 7a4992299554 ([drbd] use sock_sendmsg()) on top of that as soon as it hits the mainline. For conspiracy theorists out there (hi, Brad) - that commit (killing the modifications of iovec and reinitializing msg->iov_iter; just set it once and let sendmsg() update it in normal fashion) had been sitting around since late 2014. It happened to fix the bug in question, without a single line refering to that in commit message. Reason: I had completely missed the problem; intent of that loop had been obvious and replacement had obviously done what was intended there. What I had failed to spot was that the code in there did *not* match that intent. Replacement does. And unlike the minimal fix (either version) it doesn't belong in -stable. -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
