* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: fs: take the ACL checks to common code bury posix_acl_..._masq() variants kill boilerplates around posix_acl_create_masq() generic_acl: no need to clone acl just to push it to set_cached_acl() kill boilerplate around posix_acl_chmod_masq() reiserfs: cache negative ACLs for v1 stat format xfs: cache negative ACLs if there is no attribute fork 9p: do no return 0 from ->check_acl without actually checking vfs: move ACL cache lookup into generic code CIFS: Fix oops while mounting with prefixpath xfs: Fix wrong return value of xfs_file_aio_write fix devtmpfs race caam: don't pass bogus S_IFCHR to debugfs_create_...() get rid of create_proc_entry() abuses - proc_mkdir() is there for purpose asus-wmi: ->is_visible() can't return negative fix jffs2 ACLs on big-endian with 16bit mode_t 9p: close ACL leaks ocfs2_init_acl(): fix a leak VFS : mount lock scalability for internal mounts
