Documentation: document custom config setup
To quote Johannes Thumshirn's patch which inspired this one: "The config
file is bash and it gets sourced, so all bash magic is doable in there
as well. Document it so others don't have to re-discover this gem as
well."

blktests: use global configfs variable
This patch introduces a global variable to hold the
configfs nvmet path. Now we don't need repetitive
local variables to hold the path and testcases
can use the newly introduced variable if needed.

Apparently tracefs is lazily mounted, so try to stat
/sys/kernel/debug/tracing/trace before we check if it's mounted in order
to avoid false negatives.

Add surprise removal block test
This test is for PCI devices in a surprise remove capable slot and tests
how well the drivers and kernel handle losing the link to that device.
The test finds the PCI Express Capability register of the pci slot a block
device is in, then at offset 0x10 (the Link Control Register) writes a 1
to bit 4 (Link Disable). This occurs unbeknownst to any of the drivers,
just like a surprise removal. Drivers will find out about this through
the pcie hotplug handler, at which point it's too late to communicate
with the device, therfore testing how well we cope with the condition.
The link is reenabled at the end of the test.
Note, this is currently incompatible with NVMe Subsystems when
CONFIG_NVME_MULTIPATH since the /dev/nvme*n* names don't have a pci
parent in sysfs.

common/nvme:32:18: note: Use find instead of ls to better handle
non-alphanumeric filenames. [SC2012]
Secondly, it's not _technically_ correct to just count the number of
ports, since there could be just one port numbered 1. Instead, find the
first free port.
scsi/004: set delay in nanoseconds instead of jiffies
Steffen pointed out that "the timeout should be sufficiently larger than
scsi_debug/delay, in order not to run into the command timeout". The
delay parameter is in jiffies, so on s390 with the default HZ=100, 1000
jiffies are 10 seconds, more than the blk-mq timeout. Just use ndelay
instead.

blktests: add nbd test for online resize
This tests resizing a connected nbd device. We connect to the existing

test/nvme/003: add test case for patch "nvme: don't send keep-alives to the discovery controller"
Add a regression test for the patch titled "nvme: don't send

This patch creates a local loopback nvme target and then connects to
it. If the patch is not applied we see two error messages in dmesg:
"failed nvme_keep_alive_end_io error=" from the nvme host and "nvmet:
unsupported cmd 24" from the nvme target. If the patch is applied
dmesg is quiet.

This pull adds a new test-case to the nvme test group for testing big
discovery log pages.
It is inspired by a bug triggered in the user-space 'nvme discover' with
a non Linux target which set's an non 0 MDTS (Maximum Data Transfer
Size) value causing nvme cli to fail the discovery.
There isn't a userspace fix yet, but it's still a nice scalability test.
