 Description   

when mdt takes a grouplock (mdd_file_lock()) it allocates an ma and free it in the glimpse grouplock callback.
the cb is called for each stripe so the ma is freed multiple time
the proposed patch (gerrit will follow) is to use a global ma structure allocated out of the lock/unlock sequence

http://review.whamcloud.com/#/c/2103/ shows that the patch is still being reviewed – so I had closed it prematurely.
