Merge branch 'getname2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull getname/putname updates from Al Viro: "Rework of getname/getname_kernel/etc., mostly from Paul Moore. Gets rid of quite a pile of kludges between namei and audit..." * 'getname2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: audit: replace getname()/putname() hacks with reference counters audit: fix filename matching in __audit_inode() and __audit_inode_child() audit: enable filename recording via getname_kernel() simpler calling conventions for filename_mountpoint() fs: create proper filename objects using getname_kernel() fs: rework getname_kernel to handle up to PATH_MAX sized filenames cut down the number of do_path_lookup() callers
