Hi all,

After merging the cifs tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

<stdin>:1559:2: warning: #warning syscall futex_waitv not implemented [-Wcpp]
fs/cifs/connect.c: In function 'clean_demultiplex_info':

      |        ;
  845 |  kfree(server);
      |  ~~~~~  

Caused by commit

  58b90aa95977 ("cifs: support nested dfs links over reconnect")

I have used the cifs tree from next-20211110 for today.
