When the result of a posix lock request is read it needs to be matched up
with the correct waiting request. The owner field needs to be used in the
comparison since more than one process may be waiting for locks on the
same file.

Use the gfs2_ prefix on the register/unregister functions for the lock
modules. The gfs_ prefix was left from an old idea on how to share these
with gfs1.

We need to use fl_owner instead of fl_pid to track the owner of a posix
lock. Pass the owner value out to user space where cluster plocks are
managed.

Setup the lock_dlm kobject before setting up the dlm lockspace instead
of after. We want to use the sysfs files to detect the mount without
having to wait for the dlm setup which can take a while.

unimplemented:

This saves the journal recovery result and makes it visible through sysfs.
User space needs to know if the node actually recovered the journal or
tried and gave up.

Some interfaces have changed. In particular one of the posix
locking functions has changed prototype, along with the
address space operation invalidatepage and the block getting
callback to the direct IO function.
In addition add the splice file operations. These will need to
be updated to support AOP_TRUNCATED_PAGE before they will be
of much use to us.
