This command can be used by a sysadmin to either copy or migrate a data
file on one DS to another DS.
Its main use is to recover data files onto a mirrored DS after the DS has
been repaired and brought back online.
This command allows a sysadmin to display or modify the pnfsd.dsfile extended
attribute used by the pNFS MDS server in various ways.
Its main use is to set a DS's IP address to 0.0.0.0 when that DS has failed,
so that it will not be used for the file when brought back online after
being repaired.

The issue on arm is that smbios_detect does unaligned accesses, which

callback to do the checks.
This will allow us to have a more graceful fallback code. In the
future, it's anticipated that we may fallback to a more global search
(or implement a command to do so) when reqeusted by the user, or we
detect a violation of the UEFI Boot Manager protocol severe enough to
warrant this backstop. For now, it just allows us to get rid of img as

Summary:
Newer OPAL device trees, such as those on POWER9 systems, use 'pciex' for
device_type, not 'pci'. Rather than enumerating all possible variants, just
check for a 'pci' prefix.

This could happen with either WITHOUT_AUTO_OBJ=yes or MAKELEVEL>0 for
the initial 'make buildworld' command.
This now ensures that build-tools targets have 'make obj' ran if needed.
This is especially problematic for pmu-events since it is not directly
connected in the build. Normally the 'make includes' call right before
this implicitly creates the objdir with a 'make obj' already but
misses pmu-events because it is disconnected from lib/libpmc. Fixing that
would make this new 'make obj' pointless but it is being added to avoid
this problem in the future should another tool be connected like this.

This was the wrong solution to the problem; regulator_shutdown invokes

mmel@ has a proposed patch/solution to instead provide regnode_fixed_stop

the initial TCP SYN-ACK segment.
This patch ensures that an updated timestamp is used when sending the

SYN-ACK was retransmitted from the generic code.
This makes the behaviour consistent and also conformant with
the TCP specification.

Some clocks can have parents from other drivers, for example clocks in the
sun8i_r driver uses clocks from the main clock driver.
This worked before because the sun8i_r node is after the main ccu node in the
dtb and driver are probed in DTB order. This cannot work with the Display
Engine clocks as it is the first node in the DTB.
