From 9587fcff42f5bece3c0a44066b079235ee73cbb3 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 1 Feb 2011 08:40:43 -0500 Subject: cifs: fix length vs. total_read confusion in cifs_demultiplex_thread length at this point is the length returned by the last kernel_recvmsg call. total_read is the length of all of the data read so far. length is more or less meaningless at this point, so use total_read for everything.
