Also when a remote was removed from a fdb entry with several remotes, the deleted remote was not advertised. Signed-off-by: Nicolas Dichtel <[email protected]> Signed-off-by: David S.

The default hierarchy will serve as the unified hierarchy to which all controllers are attached and a css on the default hierarchy would need to also serve the tasks of descendant cgroups which don't have the controller enabled - ie. the tree may be collapsed from leaf towards root when viewed from specific controllers. This has been implemented through effective css in the previous patches. This patch finally implements dynamic subtree controller enable/disable on the default hierarchy via a new knob - "cgroup.subtree_control" which controls which controllers are enabled on the child cgroups. Let's assume a hierarchy like the following. root - A - B - C \ D root's "cgroup.subtree_control" determines which controllers are enabled on A. A's on B. B's on C and D. This coincides with the fact that controllers on the immediate sub-level are used to distribute the resources of the parent. In fact, it's natural to assume that resource control knobs of a child belong to its parent. Enabling a controller in "cgroup.subtree_control" declares that distribution of the respective resources of the cgroup will be controlled. Note that this means that controller enable states are shared among siblings. The default hierarchy has an extra restriction - only cgroups which don't contain any task may have controllers enabled in "cgroup.subtree_control". Combined with the other properties of the default hierarchy, this guarantees that, from the view point of controllers, tasks are only on the leaf cgroups. In other words, only leaf csses may contain tasks. This rules out situations where child cgroups compete against internal tasks of the parent, which is a competition between two different types of entities without any clear way to determine resource distribution between the two. Different controllers handle it differently and all the implemented behaviors are ambiguous, ad-hoc, cumbersome and/or just wrong. Having this structural constraints imposed from cgroup core removes the burden from controller implementations and enables showing one consistent behavior across all controllers. When a controller is enabled or disabled, css associations for the controller in the subtrees of each child should be updated. After enabling, the whole subtree of a child should point to the new css of the child. After disabling, the whole subtree of a child should point to the cgroup's css. This is implemented by first updating cgroup states such that cgroup_e_css() result points to the appropriate css and then invoking cgroup_update_dfl_csses() which migrates all tasks in the affected subtrees to the self cgroup on the default hierarchy. * When read, "cgroup.subtree_control" lists all the currently enabled controllers on the children of the cgroup. * White-space separated list of controller names prefixed with either '+' or '-' can be written to "cgroup.subtree_control". The ones prefixed with '+' are enabled on the controller and '-' disabled. * A controller can be enabled iff the parent's "cgroup.subtree_control" enables it and disabled iff no child's "cgroup.subtree_control" has it enabled. * If a cgroup has tasks, no controller can be enabled via "cgroup.subtree_control". Likewise, if "cgroup.subtree_control" has some controllers enabled, tasks can't be migrated into the cgroup. * All controllers which aren't bound on other hierarchies are automatically associated with the root cgroup of the default hierarchy. All the controllers which are bound to the default hierarchy are listed in the read-only file "cgroup.controllers" in the root directory. * "cgroup.controllers" in all non-root cgroups is read-only file whose content is equal to that of "cgroup.subtree_control" of the parent. This indicates which controllers can be used in the cgroup's "cgroup.subtree_control". This is still experimental and there are some holes, one of which is that ->can_attach() failure during cgroup_update_dfl_csses() may leave the cgroups in an undefined state. The issues will be addressed by future patches. v2: Non-root cgroups now also have "cgroup.controllers".

Update cgroup_migrate_prepare_dst() so that it accepts NULL as the destination cgrp. When NULL is specified, the destination is considered to be the cgroup on the default hierarchy associated with each css_set. After this change, the identity check in cgroup_migrate_add_src() isn't sufficient for noop detection as the associated csses may change without any cgroup association changing. The only way to tell whether a migration is noop or not is testing whether the source and destination csets are identical. The noop check in cgroup_migrate_add_src() is removed and cset identity test is added to cgroup_migreate_prepare_dst(). If it's detected that source and destination csets are identical, the cset is removed removed from @preloaded_csets and all the migration nodes are cleared which makes cgroup_migrate() ignore the cset. Also, make the function append the destination css_sets to @preloaded_list so that destination css_sets always come after source css_sets.

The intention was to clear it after offline is complete, not reassign the same value. Update it to assign NULL instead of the current value. This makes cgroup_css() to return NULL once offline is complete. All the existing users of the function either can handle NULL return already or guarantee that the css doesn't get offlined. While this is a bugfix, as css lifetime is currently tied to the cgroup it belongs to, this bug doesn't cause any actual problems.

This works fine for !unified hierarchies as each cgroup has its own css for each associated subsystem on the hierarchy; however, on the planned unified hierarchy, a cgroup may not have csses associated and its tasks would be considered associated with the matching css of the nearest ancestor which has the subsystem enabled. This means that on the default unified hierarchy, just walking all tasks associated with a cgroup isn't enough to walk all tasks which are associated with the specified css. If any of its children doesn't have the matching css enabled, task iteration should also include all tasks from the subtree. We already added cgroup->e_csets[] to list all css_sets effectively associated with a given css and walk css_sets on that list instead to achieve such iteration. This patch updates css_task_iter iteration such that it walks css_sets on cgroup->e_csets[] instead of cgroup->cset_links if iteration is requested on an non-dummy css. Thanks to the previous iteration update, this change can be achieved with the addition of css_task_iter->ss and minimal updates to css_advance_task_iter() and css_task_iter_start().

Replace it with explicit ->cset_head so that css_advance_task_iter() doesn't have to know the termination condition directly. * css_task_iter_next() currently assumes that it's walking list of cgrp_cset_link and reaches into the current cset through the current link to determine the termination conditions for task walking. As this won't always be true for effective css walking, add ->tasks_head and ->mg_tasks_head and use them to control task walking so that css_task_iter_next() doesn't have to know how css_sets are being walked.

When a cgroup doesn't have its own css for a given controller, the css of the nearest ancestor with the controller enabled will be used, which is called the effective css. This patch introduces cgroup_e_css() and for_each_e_css() to access the effective csses and convert compare_css_sets(), find_existing_css_set() and cgroup_migrate() to use the effective csses so that they can handle cgroups with partial csses correctly. This means that for two css_sets to be considered identical, they should have both matching csses and cgroups. compare_css_sets() already compares both, not for correctness but for optimization. As this now becomes a matter of correctness, update the comments accordingly. For all !default hierarchies, cgroup_e_css() always equals cgroup_css(), so this patch doesn't change behavior.

This patch restores cgroup_root->subsys_mask and morphs cgroup->subsys_mask into cgroup->child_subsys_mask. * Uses of root->cgrp.subsys_mask are restored to root->subsys_mask. * Remove automatic setting and clearing of cgrp->subsys_mask and instead just inherit ->child_subsys_mask from the parent during cgroup creation. Note that this doesn't affect any current behaviors. * Undo __kill_css() separation.

Skipping made sense when the default hierarchy was dummy; however, now that the default hierarchy is full functional and planned to be used as the unified hierarchy, it shouldn't be skipped over.

If the pin interrupts are enabled for some pins at boot, the wake-up events can show up as constantly pending at least on omaps and will hang the system unless the related device driver clears the event at the device. To fix this, let's clear the interrupt flags during init, and print out a warning so the board maintainers can update their drivers to do proper request_irq for the driver specific wake-up events.

In a case like dmaengine which's not a dai but as a component sharing an identical name with a dai, both the id and pos->num_dai here could be 0. If we break the search, we may never find the dai we want as it might be placed behind its dmaengine in the component list.
