[DLM] The core of the DLM for GFS2/CLVM This is the core of the distributed lock manager which is required to use GFS2 as a cluster filesystem. It is also used by CLVM and can be used as a standalone lock manager independantly of either of these two projects. It implements VAX-style locking modes.

dlm: clean ups A couple small clean-ups. Remove unnecessary wrapper-functions in rcom.c, and remove unnecessary casting and an unnecessary ASSERT in util.c. Signed-off-by: David Teigland <teigland@redhat.com>

dlm: use fixed errno values in messages Some errno values differ across platforms. So if we return things like -EINPROGRESS from one node it can get misinterpreted or rejected on another one. This patch fixes up the errno values passed on the wire so that they match the x86 ones (so as not to break the protocol), and re-instates the platform-specific ones at the other end. Many thanks to Fabio for testing this patch. Initial patch from Patrick. Signed-off-by: Patrick Caulfield <pcaulfie@redhat.com> Signed-off-by: Fabio M.

dlm: use __le types for dlm messages This patch changes to use __le types directly in the dlm message structure which is casted at the right dlm message buffer positions. The main goal what is reached here is to remove sparse warnings regarding to host to little byte order conversion or vice versa. Leaving those sparse issues ignored and always do it in out/in functionality tends to leave it unknown in which byte order the variable is being handled.
