I've been running quite a few tests with the converted cgroup and haven't found anything critical yet, so the outlook isn't too bad.

That's fine with me. Do you feel kernfs is good enough now for other subsystems to use? I want to port debugfs to it when ready. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

[PATCHSET v2 driver-core-next] kernfs: prepare for cgroup's kernfs conversion
Hello, This patchset makes various updates in preparation of cgroup's kernfs conversion. 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.
