-5.5 dirty memory
-
-Control the maximum amount of dirty pages a cgroup can have at any given time.
-
-Limiting dirty memory is like fixing the max amount of dirty (hard to reclaim)
-page cache used by a cgroup. So, in case of multiple cgroup writers, they will
-not be able to consume more than their designated share of dirty pages and will
-be forced to perform write-out if they cross that limit.
-
-The interface is equivalent to the procfs interface: /proc/sys/vm/dirty_*. It
-is possible to configure a limit to trigger both a direct writeback or a
-background writeback performed by per-bdi flusher threads. The root cgroup
-memory.dirty_* control files are read-only and match the contents of
-the /proc/sys/vm/dirty_* files.
-
-Per-cgroup dirty limits can be set using the following files in the cgroupfs:
-
-- memory.dirty_ratio: the amount of dirty memory (expressed as a percentage of
- cgroup memory) at which a process generating dirty pages will itself start
- writing out dirty data.
-
-- memory.dirty_limit_in_bytes: the amount of dirty memory (expressed in bytes)
- in the cgroup at which a process generating dirty pages will start itself
- writing out dirty data. Suffix (k, K, m, M, g, or G) can be used to indicate
- that value is kilo, mega or gigabytes.
-
- Note: memory.dirty_limit_in_bytes is the counterpart of memory.dirty_ratio.
- Only one of them may be specified at a time. When one is written it is
- immediately taken into account to evaluate the dirty memory limits and the
- other appears as 0 when read.
-
-- memory.dirty_background_ratio: the amount of dirty memory of the cgroup
- (expressed as a percentage of cgroup memory) at which background writeback
- kernel threads will start writing out dirty data.
-
-- memory.dirty_background_limit_in_bytes: the amount of dirty memory (expressed
- in bytes) in the cgroup at which background writeback kernel threads will
- start writing out dirty data. Suffix (k, K, m, M, g, or G) can be used to
- indicate that value is kilo, mega or gigabytes.
-
- Note: memory.dirty_background_limit_in_bytes is the counterpart of
- memory.dirty_background_ratio. Only one of them may be specified at a time.
- When one is written it is immediately taken into account to evaluate the dirty
- memory limits and the other appears as 0 when read.
-
-A cgroup may contain more dirty memory than its dirty limit. This is possible
-because of the principle that the first cgroup to touch a page is charged for
-it. Subsequent page counting events (dirty, writeback, nfs_unstable) are also
-counted to the originally charged cgroup.
-
-Example: If page is allocated by a cgroup A task, then the page is charged to
-cgroup A. If the page is later dirtied by a task in cgroup B, then the cgroup A
-dirty count will be incremented. If cgroup A is over its dirty limit but cgroup
-B is not, then dirtying a cgroup A page from a cgroup B task may push cgroup A
-over its dirty limit without throttling the dirtying cgroup B task.
-
-When use_hierarchy=0, each cgroup has dirty memory usage and limits.
-System-wide dirty limits are also consulted. Dirty memory consumption is
-checked against both system-wide and per-cgroup dirty limits.
-
-The current implementation does not enforce per-cgroup dirty limits when
-use_hierarchy=1. System-wide dirty limits are used for processes in such
-cgroups. Attempts to read memory.dirty_* files return the system-wide
-values. Writes to the memory.dirty_* files return error. An enhanced
-implementation is needed to check the chain of parents to ensure that no
-dirty limit is exceeded.
-
6. Hierarchy support
The memory controller supports a deep hierarchy and hierarchical accounting.
