[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] fix add_requestqueue checking nodes list Requests that arrive after recovery has started are saved in the requestqueue and processed after recovery is done. Some of these requests are purged during recovery if they are from nodes that have been removed. We move the purging of the requests (dlm_purge_requestqueue) to later in the recovery sequence which allows the routine saving requests (dlm_add_requestqueue) to avoid filtering out requests by nodeid since the same will be done by the purge. The current code has add_requestqueue filtering by nodeid but doesn't hold any locks when accessing the list of current nodes. This also means that we need to call the purge routine when the lockspace is being shut down since the add routine will not be rejecting requests itself any more.

[DLM] don't accept replies to old recovery messages We often abort a recovery after sending a status request to a remote node. We want to ignore any potential status reply we get from the remote node. If we get one of these unwanted replies, we've often moved on to the next recovery message and incremented the message sequence counter, so the reply will be ignored due to the seq number. In some cases, we've not moved on to the next message so the seq number of the reply we want to ignore is still correct, causing the reply to be accepted. The next recovery message will then mistake this old reply as a new one. To fix this, we add the flag RCOM_WAIT to indicate when we can accept a new reply. We clear this flag if we abort recovery while waiting for a reply. Before the flag is set again (to allow new replies) we know that any old replies will be rejected due to their sequence number. We also initialize the recovery-message sequence number to a random value when a lockspace is first created. This makes it clear when messages are being rejected from an old instance of a lockspace that has since been recreated.

[DLM] add new lockspace to list ealier When a new lockspace was being created, the recoverd thread was being started for it before the lockspace was added to the global list of lockspaces. The new thread was looking up the lockspace in the global list and sometimes not finding it due to the race with the original thread adding it to the list. We need to add the lockspace to the global list before starting the thread instead of after, and if the new thread can't find the lockspace for some reason, it should return an error.

[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] add new lockspace to list ealier When a new lockspace was being created, the recoverd thread was being started for it before the lockspace was added to the global list of lockspaces.

[DLM] fix add_requestqueue checking nodes list Requests that arrive after recovery has started are saved in the requestqueue and processed after recovery is done. Some of these requests are purged during recovery if they are from nodes that have been removed. We move the purging of the requests (dlm_purge_requestqueue) to later in the recovery sequence which allows the routine saving requests (dlm_add_requestqueue) to avoid filtering out requests by nodeid since the same will be done by the purge. The current code has add_requestqueue filtering by nodeid but doesn't hold any locks when accessing the list of current nodes. This also means that we need to call the purge routine when the lockspace is being shut down since the add routine will not be rejecting requests itself any more.

[DLM] Fix kref_put oops This patch fixes the recounting on the lockspace kobject. Previously the lockspace was freed while userspace could have had a reference to one of its sysfs files, causing an oops in kref_put.
