From 63b7d3a41ccadef971a4ffbe6662119d4275ebf9 Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Mon, 24 Dec 2012 14:41:19 +0400 Subject: CIFS: Don't let read only caching for mandatory byte-range locked files If we have mandatory byte-range locks on a file we can't cache reads because pagereading may have conflicts with these locks on the server. That's why we should allow level2 oplocks for files without mandatory locks only.
