* ocfs2: Added post handler callable function in o2net message handlerKurt Hackel2007-02-071-1/+2
| | | | | | | | | | | | | Currently o2net allows one handler function per message type. This patch adds the ability to call another function to be called after the handler has returned the message to the other node. Handlers are now given the option of returning a context (in the form of a void **) which will be passed back into the post message handler function.

* ocfs2_dlm: Cookies in locks not being printed correctly in error messagesKurt Hackel2007-02-071-4/+4
| | | | | | | | | | | | The dlm encodes the node number and a sequence number in the lock cookie. It also stores the cookie in the lockres in the big endian format to avoid swapping 8 bytes on each lock request. The bug here was that it was assuming the cookie to be in the cpu format when decoding it for printing the error message. This patch swaps the bytes before the print.

* ocfs2: fix check for locally granted state during dlmunlock()Kurt Hackel2006-08-071-1/+1
| | | | | | | | If a process requests a lock cancel but the lock has been remotely granted already then there is no need to send the cancel message. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: do not modify lksb->status in the unlock astKurt Hackel2006-08-071-25/+12

* [PATCH] OCFS2: The Second Oracle Cluster FilesystemKurt Hackel2006-01-031-0/+672
A distributed lock manager built with the cluster file system use case in mind. The OCFS2 dlm exposes a VMS style API, though things have been simplified internally. The only lock levels implemented currently are NLMODE, PRMODE and EXMODE. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com>
