From: Chen Ridong <chenridong@huawei.com>

Most of the v1-specific code has already been moved to cpuset-v1.c, but
some parts remain in cpuset.c, such as the handling of CS_SPREAD_PAGE,
CS_SPREAD_SLAB, and CGRP_CPUSET_CLONE_CHILDREN. These can also be moved
to cpuset-v1.c.

Additionally, several cpuset members are specific to v1, including
fmeter, relax_domain_level, and the uf_node node. These should only be
visible when v1 support is enabled (CONFIG_CPUSETS_V1).

This series relocates the remaining v1-specific code to cpuset-v1.c and
guards v1-only members with CONFIG_CPUSETS_V1.

The most significant change is the separation of generate_sched_domains()
into v1 and v2 versions. For v1, the original function is preserved
with v2-specific code removed, keeping it largely unchanged since v1 is
deprecated and receives minimal future updates. For v2, all v1-specific
code has been removed, resulting in a much simpler and more maintainable
implementation.

Chen Ridong (6):
  cpuset: add assert_cpuset_lock_held helper
  cpuset: add cpuset1_online_css helper for v1-specific operations
  cpuset: add cpuset1_init helper for v1 initialization
  cpuset: move update_domain_attr_tree to cpuset_v1.c
  cpuset: separate generate_sched_domains for v1 and v2
  cpuset: remove v1-specific code from generate_sched_domains
