dlm: always use GFP_NOFS

2009-11-30T22:34:43Z

Replace all GFP_KERNEL and ls_allocation with GFP_NOFS. ls_allocation would be GFP_KERNEL for userland lockspaces and GFP_NOFS for file system lockspaces. It was discovered that any lockspaces on the system can affect all others by triggering memory reclaim in the file system which could in turn call back into the dlm to acquire locks, deadlocking dlm threads that were shared by all lockspaces, like dlm_recv.

dlm: use more NOFS allocation

2009-05-15T16:24:59Z

Change some GFP_KERNEL allocations to use either GFP_NOFS or ls_allocation (when available) which the fs sets to GFP_NOFS. The point is to prevent allocations from going back into the cluster fs in places where that might lead to deadlock. Signed-off-by: David Teigland

dlm: Change rwlock which is only used in write mode to a spinlock

2009-01-28T18:55:55Z

The ls_dirtbl[].lock was an rwlock, but since it was only used in write mode a spinlock will suffice. Signed-off-by: Steven Whitehouse Signed-off-by: David Teigland

dlm: fix dlm_dir_lookup() handling of too long names

2008-02-04T07:30:19Z

... those can happen and BUG() from DLM_ASSERT() in allocate_direntry() is not a good way to handle them. Signed-off-by: Al Viro Signed-off-by: David Teigland

dlm: keep cached master rsbs during recovery

2008-01-30T17:04:43Z

To prevent the master of an rsb from changing rapidly, an unused rsb is kept on the "toss list" for a period of time to be reused. The toss list was being cleared completely for each recovery, which is unnecessary. Much of the benefit of the toss list can be maintained if nodes keep rsb's in their toss list that they are the master of. These rsb's need to be included when the resource directory is rebuilt during recovery. Signed-off-by: David Teigland

dlm: use dlm prefix on alloc and free functions

2008-01-29T23:17:19Z

The dlm functions in memory.c should use the dlm_ prefix. Also, use kzalloc/kfree directly for dlm_direntry's, removing the wrapper functions. Signed-off-by: David Teigland
