    Description

      Several customers have asked for the ability to list open files on the whole filesystem. Currently this is only possible to do on the clients by running "lsof" but is impractical to do.

      This would likely be implemented by walking all of the client exports and then listing all of the objects in med_open_head as NID_FID pairs. Userspace could then sort/print the open files as desired using "lfs fid2path".
