Fix kerneldoc warnings across the dm-vdo target. Also
remove some unhelpful or inaccurate doc comments, and fix
some format inconsistencies that did not produce warnings.

Bios are embedded into other structures, and at least spare is unhappy
about embedding structures with variable sized arrays. There's no
real need to the array anyway, we can replace it with a helper pointing
to the memory just behind the bio, and with the previous cleanups there
is very few site doing anything special with it.

The function get_volume_page_protected may place a request on
a queue for another thread to process asynchronously. When this
happens, the volume should not read the request from the original
thread. This can not currently cause problems, due to the way
request processing is handled, but it is not safe in general.

Reorder fields and make uds_request_type and uds_zone_message packed,
to squeeze out some space. Use struct_group so the request reset code
no longer needs to care about field order.
On x86_64 this reduces the struct size from 144 to 120, which saves 48
kB (about 12%) per VDO hash zone.

Clear provisional refcount values and count free/allocated blocks in
one integrated loop. Process 8 aligned bytes at a time instead of
every byte individually.
On an Intel i7-11850H this reduces the CPU time needed to process a
loaded refcount block by a factor of about 5-6. On a large system the
refcount loading may be the largest factor in device startup time.

With larger-sized metadata vio pools, vdo will sometimes need to
issue I/O with a smaller size than the allocated size. Since
vio_reset_bio is where the bvec array and I/O size are initialized,

Patch series "Enhance min heap API with non-inline functions and
optimizations", v2.
Add non-inline versions of the min heap API functions in lib/min_heap.c
and updates all users outside of kernel/events/core.c to use these
non-inline versions. To mitigate the performance impact of indirect
function calls caused by the non-inline versions of the swap and compare
functions, a builtin swap has been introduced that swaps elements based on
their size. Additionally, it micro-optimizes the efficiency of the min
heap by pre-scaling the counter, following the same approach as in
lib/sort.c. Documentation for the min heap API has also been added to the
core-api section.
This patch (of 10):
All current min heap API functions are marked with '__always_inline'.
However, as the number of users increases, inlining these functions
everywhere leads to a increase in kernel size.
In performance-critical paths, such as when perf events are enabled and
min heap functions are called on every context switch, it is important to
retain the inline versions for optimal performance. To balance this, the
original inline functions are kept, and additional non-inline versions of
the functions have been added in lib/min_heap.c.

Pull device mapper fix from Mikulas Patocka:
- Fix broken discard for device mapper VDO target
* tag 'for-6.10/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
dm vdo: replace max_discard_sectors with max_hw_discard_sectors
|
|
Commit 4f563a64732d ("block: add a max_user_discard_sectors queue
limit") changed block core to set max_discard_sectors to:
min(lim->max_hw_discard_sectors, lim->max_user_discard_sectors)
Commit 825d8bbd2f32 ("dm: always manage discard support in terms
of max_hw_discard_sectors") fixed most dm targetss to deal with
this, by replacing max_discard_sectors with max_hw_discard_sectors.
Unfortunately, dm-vdo did not get fixed at that time.
Fixes: 825d8bbd2f32 ("dm: always manage discard support in terms of max_hw_discard_sectors")

Remove use of the blk_limits_io_{min,opt} and assign the values directly
to the queue_limits structure. For the io_opt this is a completely
mechanical change, for io_min it removes flooring the limit to the
physical and logical block size in the particular caller. But as
blk_validate_limits will do the same later when actually applying the
limits, there still is no change in overall behavior.

After adding min_heap_sift_up(), the naming convention has been adjusted
to maintain consistency with the min_heap_sift_up(). Consequently,
min_heapify() has been renamed to min_heap_sift_down().
