FIMD device is not used at all on Exynos5422-based Odroid XU3-lite and
XU4. XU3 board theorethically can support FIMD with DisplayPort
connector, but due to hw limitation/design it doesn't work in most
cases. It is also not even enabled in XU3 dts file.
FIMD node was enabled mainly due to limitation of early Exynos DRM
driver, which didn't initialize properly when no FIMD device was
available. This node can be now safely removed from XU3-common dtsi and
added layer to Odroid XU3 dts, when Display Port driver gets enabled.

This watchdog is instantiated in a FPGA that is memory mapped. It is
made of only one register, called the feed register. Writing to this
register will re-arm the watchdog for a given time (and enable it if it
was disable). It can be disabled by writing a special value into it.
It is part of a syscon block, and the watchdog register offset in this
block varies from board to board. This offset is passed in the syscon
property after the phandle to the syscon node.

Currently, we will only record the layoutstats correctly if the
RPC call successfully obtains a slot. If we exit before that
happens, then we may find ourselves starting the busy timer through
the call in ff_layout_(read|write)_prepare_layoutstats, but never stopping it.
The same thing happens if we're doing DA-DS.
The fix is to ensure that we catch these cases in the rpc_release()
callback.
Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
When we replay a failed read, write or commit to the dataserver, we
need to ensure that we call ff_layout_read_prepare_v3(),

reset the statistics.

In pNFS/flexfiles, we want to return the layout without necessarily marking
it as having completely failed. We therefore move the call to
pnfs_layout_io_set_failed() out of pnfs_error_mark_layout_for_return(),

Fix a bug in which flexfiles clients are falling back to I/O through the
MDS even when the FF_FLAGS_NO_IO_THRU_MDS flag is set.
The flexfiles client will always report errors through the LAYOUTRETURN

to retry the LAYOUTGET until it fails or succeeds.
