      NFS: nfs_compare_mount_options always compare auth flavors. · 594d1644
      Chris Perl authored
      This patch removes the check from nfs_compare_mount_options to see if a
      `sec' option was passed for the current mount before comparing auth
      flavors and instead just always compares auth flavors.
      
      Consider the following scenario:
      
      You have a server with the address 192.168.1.1 and two exports /export/a
      and /export/b.  The first export supports `sys' and `krb5' security, the
      second just `sys'.
      
      Assume you start with no mounts from the server.
      
      The following results in EIOs being returned as the kernel nfs client
      incorrectly thinks it can share the underlying `struct nfs_server's:
      
      $ mkdir /tmp/{a,b}
      $ sudo mount -t nfs -o vers=3,sec=krb5 192.168.1.1:/export/a /tmp/a
      $ sudo mount -t nfs -o vers=3          192.168.1.1:/export/b /tmp/b
      $ df >/dev/null
      df: ‘/tmp/b’: Input/output error
