From 84210e9120a8c01a14379ba1f9a9b0f963641d94 Mon Sep 17 00:00:00 2001 From: Steve French Date: Thu, 23 Oct 2008 04:42:37 +0000 Subject: [CIFS] improve setlease handling fcntl(F_SETLEASE) currently is not exported by cifs (nor by local file systems) so cifs grants leases based on how other local processes have opened the file not by whether the file is cacheable (oplocked). This adds the check to make sure that the file is cacheable on the client before checking whether we can grant the lease locally (generic_setlease). It also adds a mount option for cifs (locallease) if the user wants to override this and try to grant leases even if the server did not grant oplock.
