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>
2006-06-09[DLM] compat patchPatrick Caulfield
Here's a patch which add 32/64 bit compat to the DLM IOs and tidies the structures for alignment. As it causes an ABI change I had few qualms about adding the extra flag for "is64bit" as it simply uses a byte that would have been padding.

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>
2006-05-24[GFS2] Cast 64 bit printk args to unsigned long long.David Teigland

2006-05-02[DLM] fix grant_after_purge softlockupDavid Teigland
In dlm_grant_after_purge() we were holding a hash table read_lock while calling put_rsb() which potentially removes the rsb from the hash table, taking the same lock in write. Fix this by flagging rsb's ahead of time that have been purged. Then iteratively read_lock the hash table, find a flagged rsb, unlock, process rsb.

2006-04-28[DLM] PATCH 3/3 dlm: show recover stateDavid Teigland
Expose the current recovery state in sysfs to help in debugging. Signed-off-by: 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>
2006-04-28[DLM] PATCH 1/3 dlm: force free user lockspaceDavid Teigland
Lockspaces created from user space should be forcibly freed without requiring any further user space interaction. Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-04-25[DLM] Convert a semaphore to a completionPatrick Caulfield
Convert a semaphore into a completion in device.c. Cc: David Teigland <teigland@redhat.com> Cc: Andrew Morton <akpm@osdl.org> Signed-off-by: Patrick Caulfield <pcaulfie@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-04-25[DLM] Update Kconfig in the light of comments on lkmlSteven Whitehouse
We now depend on user selectable options rather than select them. There is no dependancy on SYSFS since this selection is independant of the DLM (even though it wouldn't be sensible to build the DLM without it) Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-02-28[DLM] Pass in lockspace to lkb put functionDavid Teigland
In some cases a lockspace isn't attached to the lkb, so that it needs to be passed directly to the lkb put function. Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-02-23[DLM] Remove range locks from the DLMDavid Teigland

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.
