The Display and Video clock controllers for SM8250 are enabled, as is

Lastly the Ath11k driver, used on a variety of modern boards and the
FastRPC driver, which provides an interface for computational offloading

All drivers, except the SM8250 Display and Video clock controller

Now that filler_t and aops->read_folio() have the same type, we can decide
which one to use at the top of the function, and cache ->read_folio in
the filler parameter.
Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
By making filler_t the same as read_folio, we can use the same function
for both in gfs2. We can push the use of folios down one more level
in jffs2 and nfs. We also increase type safety for future users of the
various read_cache_page() family of functions by forcing the parameter
to be a pointer to struct file (or NULL).

CIFS should probably be converted to use netfs_read_folio() by someone
familiar with it.

mpage_readpage still works in terms of pages, and has not been audited
for correctness with large folios, so include an assertion that the
filesystem is not passing it large folios. Convert all the filesystems
to call mpage_read_folio() instead of mpage_readpage().

This function is NOT converted to handle large folios, so include
an assert that the filesystem isn't passing one in. Otherwise, use
the folio functions instead of the page functions, where they exist.
Convert all filesystems which use block_read_full_page().

Change all the callers of ->readpage to call ->read_folio in preference,
if it exists. This is a transitional duplication, and will be removed
by the end of the series.

The precision loss of reading IO start_time with jiffies_to_nsecs
instead of using a high resolution timer degrades HST path prediction
for BIO-based mpath on high load workloads.
Below, I show the utilization percentage of a 10 disk multipath with
asymmetrical disk access cost, while being exercised by a randwrite FIO
benchmark with high submission queue depth (depth=64). It is possible
to see that the HST path selection degrades heavily for high-iops in
BIO-mpath, underutilizing the slower paths way beyond expected. This
seems to be caused by the start_time truncation, which makes some IO to
seem much slower than it actually is. In this scenario ST outperforms
HST for bio-mpath, but not for mq-mpath, which already uses ktime_get_ns().
The third column shows utilization with this patch applied. It is easy
to see that now HST prediction is much closer to the ideal distribution
(calculated considering the real cost of each path).
| | ST | HST (orig) | HST(ktime) | Best |
| sdd | 0.17 | 0.20 | 0.17 | 0.18 |
| sde | 0.17 | 0.20 | 0.17 | 0.18 |
| sdf | 0.17 | 0.20 | 0.17 | 0.18 |
| sdg | 0.06 | 0.00 | 0.06 | 0.04 |
| sdh | 0.03 | 0.00 | 0.03 | 0.02 |
| sdi | 0.03 | 0.00 | 0.03 | 0.02 |
| sdj | 0.02 | 0.00 | 0.01 | 0.01 |
| sdk | 0.02 | 0.00 | 0.01 | 0.01 |

This issue was originally discussed [1] when we first merged HST, and
this patch was left as a low hanging fruit to be solved later.
Regarding the implementation, as suggested by Mike in that mail thread,
in order to avoid the overhead of ktime_get_ns for other selectors, this
patch adds a flag for the selector code to request the high-resolution
timer.
I tested this using the same benchmark used in the original HST submission.
