proc: Make the PROC_I() and PDE() macros internal to procfs
Make the PROC_I() and PDE() macros internal to procfs. This means making PDE_DATA() out of line. This could be made more optimal by storing PDE()->data into inode->i_private. Also provide a __PDE_DATA() that is inline and internal to procfs. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
