From 2a97468024fb5b6eccee2a67a7796485c829343a Mon Sep 17 00:00:00 2001 From: Petr Tesarik Date: Tue, 20 Nov 2007 02:24:08 +0000 Subject: [PATCH] [CIFS] Fix spurious reconnect on 2nd peek from read of SMB length When retrying kernel_recvmsg() because of a short read, check returned length against the remaining length, not against total length. This avoids unneeded session reconnects which would otherwise occur when kernel_recvmsg() finally returns zero when asked to read zero bytes.
