cgroup_drain_offline() is used to wait for csses being offlined to uninstall itself from cgroup->subsys[] array so that new csses can be installed. The function's only user, cgroup_subtree_control_write(), calls it after performing some checks and restarts the whole process via restart_syscall() if draining has to release cgroup_mutex to wait. This can be simplified by draining before other synchronized operations so that there's nothing to restart. This patch converts cgroup_drain_offline() to cgroup_lock_and_drain_offline() which performs both locking and draining and updates cgroup_kn_lock_live() use it instead of cgroup_mutex() if requested. This combined locking and draining operations are easier to use and less error-prone. While at it, add WARNs in control_apply functions which triggers if the subtree isn't properly drained.

While controllers are being enabled and disabled in cgroup_subtree_control_write(), the original subsystem masks are stashed in local variables so that they can be restored if the operation fails in the middle. This patch adds dedicated fields to struct cgroup to be used instead of the local variables and implements functions to stash the current values, propagate the changes and restore them recursively. Combined with the previous changes, this makes subsystem management operations fully recursive and modularlized. This will be used to expand cgroup core functionalities. While at it, remove now unused @css_enable and @css_disable from cgroup_subtree_control_write(). Signed-off-by: NTejun Heo <tj@kernel.org> Acked-by: NZefan Li <lizefan@huawei.com>

The three factored out css management operations - cgroup_drain_offline() and cgroup_apply_control_{disable|enable}() - only depend on the current state of the target cgroups and idempotent and thus can be easily made to operate on the subtree instead of the immediate children. This patch introduces the iterators which walk live subtree and converts the three functions to operate on the subtree including self instead of the children. While this leads to spurious walking and be slightly more expensive, it will allow them to be used for wider scope of operations. Note that cgroup_drain_offline() now tests for whether a css is dying before trying to drain it. This is to avoid trying to drain live csses as there can be mix of live and dying csses in a subtree unlike children of the same parent.

When a controller is enabled and visible on a non-root cgroup is determined by subtree_control and subtree_ss_mask of the parent cgroup. For a root cgroup, by the type of the hierarchy and which controllers are attached to it. Deciding the above on each usage is fragile and unnecessarily complicates the users. This patch introduces cgroup_control() and cgroup_ss_mask() which calculate and return the [visibly] enabled subsyste mask for the specified cgroup and conver the existing usages. * cgroup_e_css() is restructured for simplicity. * cgroup_calc_subtree_ss_mask() and cgroup_subtree_control_write() no longer need to distinguish root and non-root cases. * With cgroup_control(), cgroup_controllers_show() can now handle both root and non-root cases. cgroup_root_controllers_show() is removed. v2: cgroup_control() updated to yield the correct result on v1 hierarchies too. cgroup_subtree_control_write() converted.

We're in the process of refactoring cgroup and css management paths to separate them out to eventually allow cgroups which aren't visible through cgroup fs. This patch factors out cgroup_create() out of cgroup_mkdir(). cgroup_create() contains all internal object creation and initialization. cgroup_mkdir() uses cgroup_create() to create the internal cgroup and adds interface directory and file creation.

We're in the process of refactoring cgroup and css management paths to separate them out to eventually allow cgroups which aren't visible through cgroup fs.

Currently, whether a css (cgroup_subsys_state) has its interface files created is not tracked and assumed to change together with the owning cgroup's lifecycle. cgroup directory and interface creation is being separated out from internal object creation to help refactoring and eventually allow cgroups which are not visible through cgroupfs. This patch adds CSS_VISIBLE to track whether a css has its interface files created and perform management operations only when necessary which helps decoupling interface file handling from internal object lifecycle. After this patch, all css interface file management functions can be called regardless of the current state and will achieve the expected result.

css_sets are hashed by their subsys[] contents and in cgroup_init() init_css_set is hashed early, before subsystem inits, when all entries in its subsys[] are NULL, so that cgroup_dfl_root initialization can find and link to it. As subsystems are initialized, init_css_set.subsys[] is filled up but the hashing is never updated making init_css_set hashed in the wrong place. While incorrect, this doesn't cause a critical failure as css_set management code would create an identical css_set dynamically. Fix it by rehashing init_css_set after subsystems are initialized. While at it, drop unnecessary @key local variable. Signed-off-by: NTejun Heo <tj@kernel.org> Acked-by: NZefan Li <lizefan@huawei.com>

An associated css can be around for quite a while after a cgroup directory has been removed. In general, it makes sense to reset it to defaults so as not to worry about any remnants. For instance, memory cgroup needs to reset memory.low, otherwise pages charged to a dead cgroup might never get reclaimed. There's ->css_reset callback, which would fit perfectly for the purpose. Currently, it's only called when a subsystem is disabled in the unified hierarchy and there are other subsystems dependant on it. Let's call it on css destruction as well.

No internal process rule is enforced by cgroup_migrate_prepare_dst() during process migration. It tests whether the target cgroup's ->child_subsys_mask is zero which is different from "subtree_control" write path which tests ->subtree_control. This hasn't mattered because up until now, both ->child_subsys_mask and ->subtree_control are zero or non-zero at the same time. However, with the planned addition of implicit controllers, this will no longer be true. This patch prepares for the change by making cgorup_migrate_prepare_dst() test ->subtree_control instead.

for_each_subsys_which() allows iterating subsystems specified in a subsystem bitmask; unfortunately, it requires the mask to be an unsigned long l-value which can be inconvenient and makes it awkward to use a smaller type for subsystem masks.

There are three subsystem callbacks in css shutdown path - css_offline(), css_released() and css_free(). Except for css_released(), cgroup core didn't guarantee the order of invocation. css_offline() or css_free() could be called on a parent css before its children. This behavior is unexpected and led to bugs in cpu and memory controller. The previous patch updated ordering for css_offline() which fixes the cpu controller issue. While there currently isn't a known bug caused by misordering of css_free() invocations, let's fix it too for consistency. css_free() ordering can be trivially fixed by moving putting of the parent css below css_free() invocation.

If "cpuset.memory_migrate" is set, when a process is moved from one cpuset to another with a different memory node mask, pages in used by the process are migrated to the new set of nodes. This was performed synchronously in the ->attach() callback, which is synchronized against process management. Recently, the synchronization was changed from per-process rwsem to global percpu rwsem for simplicity and optimization. Combined with the synchronous mm migration, this led to deadlocks because mm migration could schedule a work item which may in turn try to create a new worker blocking on the process management lock held from cgroup process migration path. This heavy an operation shouldn't be performed synchronously from that deep inside cgroup migration in the first place. This patch punts the actual migration to an ordered workqueue and updates cgroup process migration and cpuset config update paths to flush the workqueue after all locks are released. This way, the operations still seem synchronous to userland without entangling mm migration with process management synchronization. CPU hotplug can also invoke mm migration but there's no reason for it to wait for mm migrations and thus doesn't synchronize against their completions.
