The ZNS specification introduces the concept of a Zone Capacity. A zone
capacity is an additional per-zone attribute that indicates the number of
usable logical blocks within each zone, starting from the first logical
block of each zone. It is always smaller or equal to the zone size.
With the SINGLE profile, we can set a block group's "capacity" as the same
as the underlying zone's Zone Capacity. We will limit the allocation not
to exceed in a following commit.

The function defrag_one_cluster() is able to defrag one range well
enough, we only need to do preparation for it, including:
- Clamp and align the defrag range
- Exclude invalid cases
- Proper inode locking
The old infrastructures will not be removed in this patch, as it would
be too noisy to review.

This new helper, defrag_one_cluster(), will defrag one cluster (at most
256K):
- Collect all initial targets
- Kick in readahead when possible
- Call defrag_one_range() on each initial target
With some extra range clamping.
- Update @sectors_defragged parameter
This involves one behavior change, the defragged sectors accounting is
no longer as accurate as old behavior, as the initial targets are not
consistent.
We can have new holes punched inside the initial target, and we will
skip such holes later.
But the defragged sectors accounting doesn't need to be that accurate
anyway, thus I don't want to pass those extra accounting burden into
defrag_one_range().

A new helper, defrag_one_range(), is introduced to defrag one range.
This function will mostly prepare the needed pages and extent status for
defrag_one_locked_target().
As we can only have a consistent view of extent map with page and extent
bits locked, we need to re-check the range passed in to get a real
target list for defrag_one_locked_target().
Since defrag_collect_targets() will call defrag_lookup_extent() and lock
extent range, we also need to teach those two functions to skip extent
lock. Thus new parameter, @locked, is introduced to skip extent lock if
the caller has already locked the range.

A new helper, defrag_one_locked_target(), introduced to do the real part
of defrag.
The caller needs to ensure both page and extents bits are locked, and no
ordered extent exists for the range, and all writeback is finished.
The core defrag part is pretty straight-forward:
- Reserve space
- Set extent bits to defrag
- Update involved pages to be dirty

Introduce a helper, defrag_collect_targets(), to collect all possible

caller should be responsible to ensure we don't exceed the limit.

In cluster_pages_for_defrag(), we have complex code block inside one
for() loop.
The code block is to prepare one page for defrag, this will ensure:
- The page is locked and set up properly.
- No ordered extent exists in the page range.
- The page is uptodate.
This behavior is pretty common and will be reused by later defrag
rework.
So factor out the code into its own helper, defrag_prepare_one_page(),
for later usage, and cleanup the code by a little.

When testing subpage defrag support, I always find some strange inode
nbytes error, after a lot of debugging, it turns out that
defrag_lookup_extent() is using PAGE_SIZE as size for
lookup_extent_mapping().
Since lookup_extent_mapping() is calling __lookup_extent_mapping() with
@strict == 1, this means any extent map smaller than one page will be
ignored, prevent subpage defrag to grab a correct extent map.
There are quite some PAGE_SIZE usage in ioctl.c, but most of them are
correct usages, and can be one of the following cases:
- ioctl structure size check
We want ioctl structure to be contained inside one page.
- real page operations
The remaining cases in defrag_lookup_extent() and
check_defrag_in_cache() will be addressed in this patch.

cluster_pages_for_defrag()
In function cluster_pages_for_defrag() we have a window where we unlock
page, either start the ordered range or read the content from disk.
When we re-lock the page, we need to make sure it still has the correct
page->private for subpage.
Thus add the extra PagePrivate check here to handle subpage cases
properly.

Currently btrfs_defrag_file() accepts both "struct inode" and "struct
file" as parameter. We can easily grab "struct inode" from "struct
file" using file_inode() helper.
The reason why we need "struct file" is just to re-use its f_ra.
Change this to pass "struct file_ra_state" parameter, so that it's more
clear what we really want. Since we're here, also add some comments on
the function btrfs_defrag_file().

btrfs_chunk_readonly() checks if the given chunk is writeable. It
returns 1 for readonly, and 0 for writeable. So the return argument type
bool shall suffice instead of the current type int.
Also, rename btrfs_chunk_readonly() to btrfs_chunk_writeable() as we
check if the bg is writeable, and helps to keep the logic at the parent
function simpler to understand.

Currently we use u16 bitmap to make 4k sectorsize work for 64K page
size.
But this u16 bitmap is not large enough to contain larger page size like
128K, nor is space efficient for 16K page size.
To handle both cases, here we pack all subpage bitmaps into a larger
bitmap, now btrfs_subpage::bitmaps[] will be the ultimate bitmap for
subpage usage.
Each sub-bitmap will has its start bit number recorded in
btrfs_subpage_info::*_start, and its bitmap length will be recorded in
btrfs_subpage_info::bitmap_nr_bits.
All subpage bitmap operations will be converted from using direct u16
operations to bitmap operations, with above *_start calculated.
For 64K page size with 4K sectorsize, this should not cause much
difference.
While for 16K page size, we will only need 1 unsigned long (u32) to
store all the bitmaps, which saves quite some space.
Furthermore, this allows us to support larger page size like 128K and
258K.

Qualcomm ARM64 defconfig updates for v5.16
The major change here is the disabling of the firmware loades user space
fallback, this is done as arm64 is the only platform with this flag
enabled and as a result doesn't play nice with standard distributions.
It then enables the new limits driver, which controls the hardware based
thermal mitigation on a range of Qualcomm platforms. The prima/pronto
WiFi and Bluetooth drivers are enabled to ensure these features works
out of the box, now that the last details in the dts are landed.
The new driver for acquiring sleep stats is enabled to facilitate the
various efforts on getting these platforms into low power mode.
Lastly the base SC7280 drivers needed to simply boot this platform are
enabled.

There's a warning there from a .gitignore file:
tools/perf/.gitignore: Documentation/doc.dep
This is not really a cross-reference type of warning, so
no need to report it.
In a matter of fact, it doesn't make sense at all to even
parse hidden files, as some text editors may create such
files for their own usage.
So, just ignore everything that matches this pattern:
/\.*

Commit 5c67aa59bd8f ("mmc: sdhci-pci: Remove dead code (struct
sdhci_pci_data et al)") removes ./include/linux/mmc/sdhci-pci-data.h;
so, there is no further file that matches 'include/linux/mmc/sdhci*'.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains:
warning: no file matches F: include/linux/mmc/sdhci*
Drop this obsolete file pattern in SECURE DIGITAL HOST CONTROLLER
INTERFACE (SDHCI) DRIVER.

While mmc0 enter suspend state, we need halt CQE to send legacy cmd(flush
cache) and disable cqe, for resume back, we enable CQE and not clear HALT
state.
In this case MediaTek mmc host controller will keep the value for HALT
state after CQE disable/enable flow, so the next CQE transfer after resume
will be timeout due to CQE is in HALT state, the log as below:

Even though there are candiates value if can't find best value, it's
returned -EIO. It's not proper behavior.
If there is not best value, use a first candiate value to work eMMC.
