6.7-stable review patch. If anyone has any objections, please let me know. ------------------ From: Shyam Prasad N <sprasad@xxxxxxxxxxxxx> [ Upstream commit fc43a8ac396d302ced1e991e4913827cf72c8eb9 ] cifs_pick_channel today just selects a channel based on the policy of least loaded channel. However, it does not take into account if the channel needs reconnect. As a result, we can have failures in send that can be completely avoided. This change doesn't make a channel a candidate for this selection if it needs reconnect.
