If a system does not provide a persistent_clock(), the time
will be updated on resume by rtc_resume(). With the addition
of the non-stop clocksources for suspend timing, those systems
set the time on resume in timekeeping_resume(), but may not
provide a valid persistent_clock().
From: Xunlei Pang
When there's no persistent clock, normally timekeeping_suspend_time
should always be zero, but this can break in timekeeping_suspend().
At T1, there was a system suspend, so old_delta was assigned T1.
After some time, one time adjustment happened, and xtime got the
value of T1-

This name is way too generic. Please make it clear it's part of a
cgroup controller.

Please make css the first element. The above prevents css <->

The blocks of nat pages to be scanned will be readahead when build free
nids. The start blkno will be adjusted to 0 when the intended range over
max_nids, then function ra_meta_pages readahead the right blkno, however,
function get_current_nat_page which is called in build_free_nids still
get t
Node/Meta inode numbers are also should not be reused, this patch
guarantee it.

nm_i->nat_tree_lock is used to sync both the operations of nat entry
cache tree and nat set cache tree, however, it isn't held when flush
nat entries during checkpoint which lead to potential race, this patch
fix it by holding the lock when gang lookup nat set cache and delete
item from nat set

Hmmm? So, now the task is visible on cgroup side before the point of
no return? What happens

Mvebu_pcie_scan_bus() is not necessary, we could use
pci_common_init_dev() instead of pci_common_init(),
and pass the device pointer as the parent. Then
pci_scan_root_bus() will be called to scan the pci busses.

Introduce pci_host_bridge_list to manage pci host
bridges in system, so we could detect whether
the host in domain:bus is alreay registered.
Then we could remove bus alreay exist test in
__pci_create_root_bus().

drivers/pci/host-bridge
This patch separate pci_host_bridge creation out
of pci_create_root_bus(), and try to make a generic
pci_host_bridge, then we could place generic PCI
infos like domain number in it. Also Ripping out
pci_host_bridge creation from pci_create_root_bus()
make code more better readability. Further more,
Introduce new scan function pci_scan_host_bridge() to
support host bridge drivers that need to provide platform
own pci_host_bridge_ops.

Now pci_bus_add_devices() has been ripped out
from pci_scan_root_bus(), we could use pci_scan_root_bus()
instead of pci_create_root_bus() + pci_scan_child_bus()
for simplicity.
