dlm: detect available userspace daemon2008-08-28T16:49:43ZDavid Teigland2008-08-18T16:43:30Zurn:sha1:dc68c7ed362a00a48290252573a8eb9f74463c3a
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 creates2008-08-28T16:49:15ZDavid Teigland2008-08-06T18:30:24Zurn:sha1:0f8e0d9a317406612700426fad3efab0b7bbc467
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.

A couple of unlikely error conditions were missing a kfree on the error
exit path.

user.c. ) Through proc->flags is read.

a) in device_write(): add sentinel NUL byte, making sure that lspace.name will
be NUL-terminated
b) in compat_input() be keep it simple about the amounts of data we are copying.
