@ -1245,13 +1245,17 @@ PAGE_SIZE multiple when read back.
This is a simple interface to trigger memory reclaim in the
target cgroup.
This file accepts a string which contains the number of bytes to
reclaim.
This file accepts a single key, the number of bytes to reclaim.
No nested keys are currently supported.
Example::
echo "1G" > memory.reclaim
The interface can be later extended with nested keys to
configure the reclaim behavior. For example, specify the
type of memory to reclaim from (anon, file, ..).
Please note that the kernel can over or under reclaim from
the target cgroup. If less bytes are reclaimed than the
specified amount, -EAGAIN is returned.
@ -1263,13 +1267,6 @@ PAGE_SIZE multiple when read back.
This means that the networking layer will not adapt based on
reclaim induced by memory.reclaim.
This file also allows the user to specify the nodes to reclaim from,
via the 'nodes=' key, for example::
echo "1G nodes=0,1" > memory.reclaim
The above instructs the kernel to reclaim memory from nodes 0,1.
memory.peak
A read-only single value file which exists on non-root

state is final and avoid missing dirty pages from another ioctl ordered
after the bitmap collection.
NOTE: One example of using the backup bitmap is saving arm64 vgic/its
tables through KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_SAVE_TABLES} command on
KVM device "kvm-arm-vgic-its" when dirty ring is enabled.
NOTE: Multiple examples of using the backup bitmap: (1) save vgic/its
tables through command KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_SAVE_TABLES} on
KVM device "kvm-arm-vgic-its". (2) restore vgic/its tables through
command KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_RESTORE_TABLES} on KVM device
"kvm-arm-vgic-its". VGICv3 LPI pending status is restored. (3) save
vgic3 pending table through KVM_DEV_ARM_VGIC_{GRP_CTRL, SAVE_PENDING_TABLES}
command on KVM device "kvm-arm-vgic-v3".
