Change the data type of start and end time IO accounting variables in,
block layer, from "unsigned long" to "u64". This is to enable nano-seconds
granularity, in next commit, for the devices whose latency is less than
milliseconds.
Changes from V2 to V3
=====================
1. Changed all the required variables data-type to u64 as part of this
first patch
2. Create a new setting '2' for iostats in sysfs in next patch
3. Change the code to get the ktime values when iostat=2 in next patch

Problem Desc
============
The "iostat" user-space utility was showing %util as 100% for the disks
which has latencies less than a milli-second i.e for latencies in the
range of micro-seconds and below.
Root Cause
==========
The IO accounting in block layer is currently done by updating the
io_ticks in jiffies which is of milli-seconds granularity. Due to this,
for the devices with IO latencies less than a milli-second, the latency
will be accounted as 1 milli-second even-though its in the range of
micro-seconds. This was causing the iostat command to show %util
as 100% which is incorrect.
Recreationg of the issue
========================
Setup

Solution
========
Use ktime_get_ns() to update the disk_stats io_ticks so that the io_ticks
are updated for every io start and end times.
Issues using ktime
==================
Using ktime_get_ns() has a performance overhead as ktime will go ahead
and reads the clock everytime its called. Following test environment
was used by Jens Axboe on which t/io_uring was run which has shown a
high performance drop.
Devices
-------
SSDs: P5800X
No of devices: 24
io_uring config
---------------
Polled IO
iostats: Enabled
Reads: Random
Block Size: 512
QDepth: 128
Batch Submit: 32
Batch Complete: 32
No of Threads: 24
With the above environment and ktime patch, it has shown a performance
drop of ~25% from iostats disabled and ~19% performance drop from current
iostats enabled. This performance drop is high.
Suggestion from Jens Axboe
==========================
Jens Axboe suggested to split the bigger patch into two as follows:
1. In first patch, change all the types from unsigned long to u64, that
can be done while retaining jiffies.
2. In second patch, add an iostats == 2 setting, which enables the higher
resolution mode using ktime. We'd still default to 1, lower granularity
iostats enabled.
Fix details
===========
1. Use ktime_get_ns() to get the current nano-seconds to update the
io_ticks for start and end time stamps in block layer for io accounting
2. Create a new setting '2' in sysfs for iostats variable i.e for
/sys/block/<device-name>/queue/iostats, to enable the iostat (io
accounting) with nano-seconds (using ktime) granularity. This setting
should be enabled only if the iostat is needed with high resolution
mode as it has a high performance drop
3. Earlier available settings were 0 and 1 for disable and enable io
accounting with milli-seconds granularity (jiffies)
Testing
=======
Ran the t/io_uring command with following setup:
Devices

------------
iostat=0, with patch: Maximum IOPS=10.09M
iostat=1, with patch: Maximum IOPS=9.84M
iostat=2, with patch: Maximum IOPS=9.48M
Changes from V2 to V3
=====================
1. Changed all the required variables data-type to u64 as a first patch
2. Create a new setting '2' for iostats in sysfs in this patch
3. Change the code to get the ktime values when iostat=2, in this patch

I don't think you can rely on the blk_queue_precise_io_stat() flag in
the completion side. The user can toggle this with data in flight, which
means the completion may use different tick units than the start. I
think you'll need to add a flag to the request in the start accounting
side to know which method to use for the completion.

With the user able to change the precision at will, I think these
io_ticks need to have a consistent unit size. Mixing jiffies and nsecs
is going to create garbage stats output. Could existing io_ticks using
jiffies be converted to jiffies_to_nsecs() so that you only have one
unit to consider?

I don't think you can rely on the blk_queue_precise_io_stat() flag in the completion side. The user can toggle this with data in flight, which means the completion may use different tick units than the start. I think you'll need to add a flag to the request in the start accounting side to know which method to use for the completion.
[GULAM]: As per my understanding, this may work for a single request_queue implemetation. But this request based accounting, as per my understanding, may be an issue with the Multi-QUEUE as there is a separate queue for each CPU and the time-stamp being recorded for the block device is a global one. Also, the issue you mentioned about the start and end accounting may update the ticks in different
units for the inflight IOs, may be just for a while. So, even if it works for MQ, I am trying to understand how much is it feasible to do this request-based change for an issue which may be there for just a moment?
So, can you please correct me if I am wrong and explore more on your suggestion so that I can understand properly?

With the user able to change the precision at will, I think these io_ticks need to have a consistent unit size. Mixing jiffies and nsecs is going to create garbage stats output. Could existing io_ticks using jiffies be converted to jiffies_to_nsecs() so that you only have one unit to consider?
[GULAM]: I am not sure if this will work as we just multiply with 1000000 to convert jiffies to nano-seconds.

nvme-mpath now also has stats, so struct nvme_request should also be
updated.

Would prefer to see blk_get_iostat_ticks tagged with 'static inline'
and moved to blkdev.h (obviously below blk_queue_precise_io_stat).
Also, just a general comment: I've historically been a bigger (ab)user
of jump_labels to avoid excess branching costs per IO, e.g. see commit
442761fd2b29 ("dm: conditionally enable branching for less used features").
It could be there is an opportunity for a follow-on patch that
leverages them? Or should that just be left to each driver to decide
to do with its own resources (rather than have block core provide that)?
(if nothing in the system ever uses QUEUE_FLAG_PRECISE_IO_STAT then
it'd be nice to avoid needless branching).

The above seems correct, by checking the top-level DM device's
disposition on QUEUE_FLAG_PRECISE_IO_STAT, but I'm now wondering
if there should be code that ensures consistency across stacked
devices (which DM is the biggest creator/consumer of)?
dm_table_set_restrictions() deals with such inconsistencies at DM
device creation time (so basically: if any device in the DM table has
QUEUE_FLAG_PRECISE_IO_STAT set then the top-level DM device should
inherit that queue flag). A user could still override it but at least
the default will be sane initially.
