From cb7e9eabb2b584884db0d11ae0376d31ac1cfdc1 Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Thu, 5 Jun 2014 19:03:27 +0400 Subject: CIFS: Use multicredits for SMB 2.1/3 writes If we negotiate SMB 2.1 and higher version of the protocol and a server supports large write buffer size, we need to consume 1 credit per 65536 bytes. So, we need to know how many credits we have and obtain the required number of them before constructing a writedata structure in writepages and iovec write.
