Hi，
In Linux 3.18 kenrel, when fstrim a ocfs2 file system, fstrim shows IO

Instead of getting the cluster list from controld, we get the list
directly from Corosync's cmap.
This introduces a new config flag BUILD_CMAP_SUPPORT, which
translates to HAVE_CMAP defines for libo2cb.

Hi,
The following series of patches updates ocfs2-tools to work with the latest
userspace clustering releases from SUSE. Kernel clustering (o2cb)
functionality is not changed.
The first 3 patches teach ocfs2-tools about the nocontrold feature
which Goldwyn implemented last year.

This requires dlm_lt libraries and they have been added wherever
required.
Note, we can possibly remove runtime load of dlm_lt and should use
compile time options. We are detecting the presence of libdlm during
compile time anyways.

This happens only the first time.
mount.ocfs2 reads the stack from the filesystems superblock. If the
stack is not setup, it will modprobe the modules and write the
appropriate stack name to cluster_stack file.
If it is already present, it tries to
