dlm: fix shutdown cleanup

2008-11-13T19:22:34+00:00

Fixes a regression from commit 0f8e0d9a317406612700426fad3efab0b7bbc467,
"dlm: allow multiple lockspace creates".

An extraneous 'else' slipped into a code fragment being moved from
release_lockspace() to dlm_release_lockspace().  The result of the
unwanted 'else' is that dlm threads and structures are not stopped
and cleaned up when the final dlm lockspace is removed.  Trying to
create a new lockspace again afterward will fail with
"kmem_cache_create: duplicate cache dlm_conn" because the cache
was not previously destroyed.

dlm: detect available userspace daemon

2008-08-28T16:49:43+00:00

If dlm_controld (the userspace daemon that controls the setup and
recovery of the dlm) fails, the kernel should shut down the lockspaces
in the kernel rather than leaving them running.  This is detected by
having dlm_controld hold a misc device open while running, and if
the kernel detects a close while the daemon is still needed, it stops
the lockspaces in the kernel.

Knowing that the userspace daemon isn't running also allows the
lockspace create/remove routines to avoid waiting on the daemon
for join/leave operations.

dlm: allow multiple lockspace creates

2008-08-28T16:49:15+00:00

Add a count for lockspace create and release so that create can
be called multiple times to use the lockspace from different places.
Also add the new flag DLM_LSFL_NEWEXCL to create a lockspace with
the previous behavior of returning -EEXIST if the lockspace already
exists.

.exit.text, saves memory.

dlm: use dlm prefix on alloc and free functions

2008-01-29T23:17:19+00:00

The dlm functions in memory.c should use the dlm_ prefix.  Also, use
kzalloc/kfree directly for dlm_direntry's, removing the wrapper functions.

Kobject: convert fs/* from kobject_unregister() to kobject_put()

2008-01-25T04:40:40+00:00

There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with
kobject_put().

Kobject: change GFS2 to use kobject_init_and_add

2008-01-25T04:40:26+00:00

Stop using kobject_register, as this way we can control the sending of
the uevent properly, after everything is properly initialized.
