      simpler calling conventions for filename_mountpoint()

Paul Moore (5):
      fs: rework getname_kernel to handle up to PATH_MAX sized filenames
      fs: create proper filename objects using getname_kernel()
      audit: enable filename recording via getname_kernel()
      audit: fix filename matching in __audit_inode() and __audit_inode_child()
      audit: replace getname()/putname() hacks with reference counters
