This patch moves the dlm_purge_lkb_callbacks() function from ast to user dlm module as it is only a function being used by dlm user implementation. I got be hinted to hold specific locks regarding the callback handling for dlm_purge_lkb_callbacks() but it was false positive. It is confusing because ast dlm implementation uses a different locking behaviour as user locks uses as DLM handles kernel and user dlm locks differently. To avoid the confusing we move this function to dlm user implementation. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>
