From 34e8ccf9ce24b6b2e275bbe35cd392e18fbbd369 Mon Sep 17 00:00:00 2001 From: David Disseldorp Date: Mon, 3 Apr 2023 11:29:55 +0200 Subject: ksmbd: set NegotiateContextCount once instead of every inc There are no early returns, so marshalling the incremented NegotiateContextCount with every context is unnecessary.
