Hello,
This patchset makes various updates in preparation of cgroup's kernfs conversion. This patchset contains the following 9 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
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.
This patchset is on top of
linus#master 54c0a4b46150 ("Merge branch 'akpm' (incoming from Andrew)") + [1] [PATCHSET v4 driver-core-next] kernfs, sysfs, driver-core: implement synchronous
