[ Upstream commit 19eb1650afeb1aa86151f61900e9e5f1de5d8d02 ]
If a thinpool set fail_io while suspending, resume will fail with:
device-mapper: resume ioctl on vg-thinpool failed: Invalid argument
The thin-pool also can't be removed if an in-flight bio is in the
deferred list.
This can be easily reproduced using:
echo "offline" > /sys/block/sda/device/state
dd if=/dev/zero of=/dev/mapper/thin bs=4K count=1
dmsetup suspend /dev/mapper/pool
mkfs.ext4 /dev/mapper/thin
dmsetup resume /dev/mapper/pool
The root cause is maybe_resize_data_dev() will check fail_io and return
error before called dm_resume.
Fix this by adding FAIL mode check at the end of pool_preresume().

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.
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.
