ocfs2/dlm: dlmlock_remote() needs to account for remastery
In dlmlock_remote(), we wait for the resource to stop being active before
setting the inprogress flag. Active includes recovery, migration, etc.
The problem here is that if the resource was being recovered or migrated, the
new owner could very well be that node itself (and thus not a remote node).
This problem was observed in Oracle bug#12583620. The error messages observed
were as follows:
dlm_send_remote_lock_request:337 ERROR: Error -40 (ELOOP) when sending message 503 (key 0xd6d8c7) to node 2
dlmlock_remote:271 ERROR: dlm status = DLM_BADARGS
dlmlock:751 ERROR: dlm status = DLM_BADARGS
