Changes from the last take[L] are * Refreshed on top of v3.14-rc1. * 0010-kernfs-add-CONFIG_KERNFS.patch added. This patchset contains the following 10 patches. 0001-kernfs-invoke-dir_ops-while-holding-active-ref-of-th.patch 0002-kernfs-rename-kernfs_dir_ops-to-kernfs_syscall_ops.patch 0003-kernfs-implement-kernfs_syscall_ops-remount_fs-and-s.patch 0004-kernfs-add-missing-kernfs_active-checks-in-directory.patch 0005-kernfs-allow-nodes-to-be-created-in-the-deactivated-.patch 0006-kernfs-implement-kernfs_ops-atomic_write_len.patch 0007-kernfs-add-kernfs_open_file-priv.patch 0008-kernfs-implement-kernfs_node_from_dentry-kernfs_root.patch 0009-kernfs-implement-kernfs_get_parent-kernfs_name-path-.patch 0010-kernfs-add-CONFIG_KERNFS.patch 0001-0003 update kernfs_dir_ops for active ref protection, add additional syscall operations and rename the struct to kernfs_syscall_ops. 0004-0005 implement an option to create new kernfs_nodes in deactivated state so that multiple nodes can be made visible atomically or removed without ever being visible to userland. 0006 implements kernfs_ops->atomic_write_len which will be used to support cgroup cftype->max_write_len. 0007 adds kernfs_open_file->priv. 0008-0009 add various helpers and accessors. 0010 adds CONFIG_KERNFS so that kernfs can be selected independently from sysfs.
