D'oh.  I guess that fs_cursor_next_entry is the next candidate:

355 /*
356  * Given a directory, match it up to a filesystem mount point.
357  */
358 static struct fs_path *
359 fs_mount_point_from_path(
360         const char      *dir)
361 {
362         fs_cursor_t     cursor;
363         fs_path_t       *fs;
364         dev_t           dev = 0;
365             
366         if (fs_device_number(dir, &dev))
367                 return NULL;
368                     
369         fs_cursor_initialise(NULL, FS_MOUNT_POINT, &cursor);
370         while ((fs = fs_cursor_next_entry(&cursor))) {
371                 if (fs->fs_datadev == dev)
372                         break;
373         }
374         return fs;
375 }

Hmm.  There are some recent commits that look related.  Commit 36298cced and
19473a2ac.  Can you try with this code?

Nope.  Looks ok to me.
