* ocfs2: pending mastery asserts and migrations should block each otherKurt Hackel2006-06-26
| | | | | | | | | Use the existing structure for blocking migrations when ASTs are pending to achieve the same result. If we can catch the assert before it goes on the wire, just cancel it and let the migration continue.

* ocfs2: temporarily disable automatic lock migrationKurt Hackel2006-06-26
| | | | | | | | | Now we never change the owner of a lock resource until unmount or node death. This will be re-enabled once some issues in the algorithm used have been resolved. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: do not unconditionally purge the lockres in dlmlock_remote()Kurt Hackel2006-06-26
| | | | | | | | | In dlmlock_remote(), do not call purge_lockres until the lock resource actually changes. otherwise, the mastery info on the lockres will go away underneath the caller. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: increase backoff before waiting for recoveryKurt Hackel2006-06-26
| | | | | | | | | When mastering non-recovery lock resources, additional time was frequently needed to allow the disk heartbeat to catch up with the network timeout. the recovery lock resource is time critical and avoids this path.

* [PATCH] ocfs2: Alloc at least a page for the DLM hashJoel Becker2006-06-26
| | | | | | | | | The OCFS2 DLM allocates a number of pages for a hash to lookup locks. There was a bug where a PAGE_SIZE bigger than the hash size (eg, 64K pages) would result in zero pages allocated.

| * Clean up 'inline is not at beginning' warnings for usb storageJesper Juhl2006-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Usually we don't care much about 'gcc -W' warnings, but some of us do build kernels that way to look for problems, and then the fewer warnings we have to wade through the better. Especially when they are very easy and non-intrusive to clean up. Which is the case for the following warnings spewed by drivers/usb/storage/usb.h : drivers/usb/storage/usb.h:163: warning: `inline' is not at beginning of +declaration drivers/usb/storage/usb.h:166: warning: `inline' is not at beginning of +declaration There's also some precedence for cleaning up these warnings.
