Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull pile 2 of vfs updates from Al Viro: "Stuff in this one - assorted fixes, lglock tidy-up, death to lock_super(). There'll be a VFS pile tomorrow (with patches from Jeff Layton, sanitizing getname() and related parts of audit and preparing for ESTALE fixes), but I'd rather push the stuff in this one ASAP - some of the bugs closed here are quite unpleasant." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: vfs: bogus warnings in fs/namei.c consitify do_mount() arguments lglock: add DEFINE_STATIC_LGLOCK() lglock: make the per_cpu locks static lglock: remove unused DEFINE_LGLOCK_LOCKDEP() MAX_LFS_FILESIZE definition for 64bit needs LL... tmpfs,ceph,gfs2,isofs,reiserfs,xfs: fix fh_len checking vfs: drop lock/unlock super ufs: drop lock/unlock super sysv: drop lock/unlock super hpfs: drop lock/unlock super fat: drop lock/unlock super ext3: drop lock/unlock super exofs: drop lock/unlock super dup3: Return an error when oldfd == newfd. fs: handle failed audit_log_start properly fs: prevent use after free in auditing when symlink following was denied
