I've updated the series with the comments from the last round.
changes
v4:
- renamed test
- updated commit messages
- fixed whitespace damage
- fixed ShellCheck reports
- dropped 'limit number of random jobs'
- fio runtime 'invinity' changed to 1d
- fixed typo and updated documentation
- added tags
v3:
- 'nvme/rc' instead of 'nvme-rc' subject prefi x
- fixed spaces vs tabs indention
- nvme/014, nvme/015 dropped -1 in #block calculation
- common/xfs: use 'tail -1' instead 'awk'
- common/xfs: no need for printf for integer division
- nvme/035 limit disk size via nvme_img_size
- set defaults to previous values: nvme_img_size=1G, nvme_num_iter=1000
- nvme/032, nvme/040 let fio figure out image size
set timeout to infinity
cleanup fio
- add documentation for nvme_tr_type, nvme_img_size and nvme_num_iter
- limited nproc to 32 for num jobs for random fio job
- drop job size limit calculation
- drop nvme_num_iter from nvme/002
- limit xfs fio job size inside _xfs_run_fio_verify_io()
- added reviewed tags
- https://lore.kernel.org/linux-nvme/20230503080258.14525-1-dwagner@suse.de/
v2:
- made image size configurable via nvme_img_size env
- make number of iteration configurable via nvme_num_iter
- do not hard code test values
- calculate job size
- use runtime for fio background jobs
- https://lore.kernel.org/linux-nvme/20230421060505.10132-1-dwagner@suse.de/
v1:
- initial version
- https://lore.kernel.org/linux-nvme/20230419085643.25714-1-dwagner@suse.de/

Introduce a convert_to_mb() helper which converts the size argument
to MBytes and use in test device require function. This makes it
possible to use user input strings in future.

Read the block device sizes instead hard coding them,
so that the device size can be configurable in future.

Make the size argument optional by reading the filesystem info. The
caller doesn't have to guess (or calculate) how big the max IO size.
The log data structure of XFS is reducing the capacity.

The usable capacity of the filesystem is less than the raw
partition/device size due to the additional meta/log data.
Ensure that the job size for fio is not exceeding the limits.
Because we have hard coded the path where we mount the filesystem
and don't want to expose this, we just update max size inside
_xfs_run_fio_verify_io(). No need to leak this into the caller.

The fio jobs are supposed to run long in background during the test.
Instead relying on a job size use explicit runtime for this.

The reduce the overall runtime of the testsuite by making the default
size of the test image small. For verification jobs, the default can be
overwriten via the newly introduced nvme_img_size environment variable.

Some tests need a minimal test image size to work correctly. Thus add a
helper to check the size and update these tests accordingly.
The image minimum is 4M because some of the test have hard coded values.
All tests which use the xfs fio verification job have a minimum
requirement of 350M impossed by the xfs filesystem.

_nvme_calc_run_io_size() returns the jobs size for _run_fio_rand_io()
function. The jobs size is the size per job, thus we have to divide
through the number of CPUs.
_xfs_run_fio_verify_io() is replaced with _run_fio_rand_io() because the
former has a minimum nvme_img_size of 350M. Both tests nvme/{045,047}
just want some IO to verify that the path is working. Thus reduce the
min nmve_img_size requirement switch to _run_fio_rand_io()

Move the discovery generation counter code to rc so that we can reuse
it in 002.

make sense for the xfs fio verify, looks good.

Is there any issue with the exiting approach for this change ?

sorry I didn't understand why we have to divide through number of
CPUs ? isn't tht will change the current job size of the test ?
unless we are increasing somewhere which I missed it .

The expectation of the test here is that there is a background job running.
Depending on the job size is an indirect way to express run at least for x
seconds. This gives a variable runtime as it depends the how fast fio jobs gets
executed. Explicitly telling the runtime is my opinion more robust and documents
the indention better.

agree, it is better to kill on rely on the variable while test is
running ...

This change reduces the I/O size per job, but it keeps the total I/O size
regardless of the number of CPUs. This will keep test case runtime reasonable
on systems with hundreds of CPUs.
As for the test case nvme/045, it tests re-authentication. I don't think it
requires total I/O size proportional to number of CPUs. As for the test case
nvme/047, it exercises different queue types (write queue and poll queue). Does
it require total I/O size proportional to number of CPUs? Daniel is the test
case author, and I guessed he is ok with the change.
