Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull vfs fix from Al Viro:
 "Followup to procfs-seq_file series this window"

This fixes a memory leak by making sure that proc seq files release any
private data on close.  The 'proc_seq_open' has to be properly paired
with 'proc_seq_release' that releases the extra private data.

  proc: add proc_seq_release
