2006-10-20[DLM] fix iovec length in recvmsgPatrick Caulfield
I didn't spot that the msg_iovlen was set to 2 if there were two elements in the iovec but left at zero if not :( I think this might be why bob was still seeing trouble. Signed-Off-By: Patrick Caulfield <pcaulfie@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-10-12[DLM] fix iovec length in recvmsgPatrick Caulfield
The DLM always passes the iovec length as 1, this is wrong when the circular buffer wraps round. Signed-Off-By: Patrick Caulfield <pcaulfie@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2006-08-11[DLM] move kmap to after spin_unlockDavid Teigland
Doing the kmap() while holding the spinlock was causing recursive spinlock problems. It seems the kmap was scheduling, although there was no warning as I'd expect. Patrick, do we need locking around the kmap? Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-06-19[DLM] init rwsem earlierDavid Teigland
The nodeinfo_lock rwsem needs to be initialized when the module is loaded instead of when the dlm is first used. Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-05-25[GFS2] Change name due to local_nodeid being a macroSteven Whitehouse
Change names of local_nodeid to dlm_local_nodeid to prevent a namespace collision. Changed other local variable to match. Cc: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-04-28[DLM] PATCH 2/3 dlm: lowcomms closeDavid Teigland
When a node is removed from a lockspace configuration, close our connection to it, clearing any remaining messages for it. Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Patrick Caulfield <pcaulfie@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-01-18[DLM] The core of the DLM for GFS2/CLVMDavid Teigland
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.
