Josef Bacik 71e9690b59 blk-iolatency: truncate our current time
In our longer tests we noticed that some boxes would degrade to the
point of uselessness.  This is because we truncate the current time when
saving it in our bio, but I was using the raw current time to subtract
from.  So once the box had been up a certain amount of time it would
appear as if our IO's were taking several years to complete.  Fix this
by truncating the current time so it matches the issue time.  Verified
this worked by running with this patch for a week on our test tier.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
