is not enough to detect a hanging or bad connection as expected of a
timeout.
This patch redesigns the timeout detection to include some more cases.
The timeout is now in relation to replies from the server. If the server

pinctl and pad-select fields are board specific, so move to

Hi Chanwoo,
Thanks for this patch. Similar patch[1] was posted long back, and there
were some concern from your side, if you think those concerns are fixed,
then my patch [1] are still valid and can be taken. If it needs to be
rebase I am happy to do that.

With current implementation, all CPUs within a NUMA node will be
assocaited with another NUMA node if the node has no memory installed.
For example, on a four-node system, CPUs on node 2 and 3 are associated
with node 0 when are no memory install on node 2 and 3, which may

Voltage tolerance isn't necessarily same on both sides of the target

When direct read IO is submitted from kernel, it is often
unnecessary to dirty pages, for example of loop, dirtying pages
have been considered in the upper filesystem(over loop) side
already, and they don't need to be dirtied again.
So this patch doesn't dirtying pages for ITER_BVEC/ITER_KVEC

If loop block is mounted via 'mount -o loop', it isn't easy
to pass file descriptor opened as O_DIRECT, so this patch
introduces a new command to support direct IO for this case.
