[2.6 patch] ocfs2: rename user_stack{,_ops}

[Adrian Bunk]

On frv and ia64 asm/ptrace.h offers a different user_stack resulting in 
compile errors like the following:

<--  snip  -->

...
  CC [M]  fs/ocfs2/stack_user.o
/home/bunk/linux/kernel-2.6/git/linux-2.6/fs/ocfs2/stack_user.c:156: error: 'user_stack' redeclared as different kind of symbol
include2/asm/ptrace.h:77: error: previous declaration of 'user_stack' was here
make[3]: *** [fs/ocfs2/stack_user.o] Error 1

<--  snip  -->

This patch therefore prefixes the user_stack{,_ops} names with ocfs2_
