      fix open/umount race · d893f1bc
      Al Viro authored
      nameidata_to_filp() drops nd->path or transfers it to opened
      file.  In the former case it's a Bad Idea(tm) to do mnt_drop_write()
      on nd->path.mnt, since we might race with umount and vfsmount in
      question might be gone already.
      Fix: don't drop it, then...  IOW, have nameidata_to_filp() grab nd->path
      in case it transfers it to file and do path_drop() in callers.  After
      they are through with accessing nd->path...
