ext4_check_geometry()
These two checkings are more suitable to be put into
ext4_check_geometry() rather than spreading outside.

The naming styles are different for some functions with 'check' in their
names. Some of them are like:
ext4_check_quota_consistency
ext4_check_test_dummy_encryption
ext4_check_opt_consistency
ext4_check_descriptors
ext4_check_feature_compatibility
While the others looks like below:
ext4_geometry_check
ext4_journal_data_mode_check
This is not a big deal and boils down to personal preference. But I'd
like to make them consistent.

Jakub Kicinski says:
====================
page_pool: allow caching from safely localized NAPI
I went back to the explicit "are we in NAPI method", mostly
because I don't like having both around :( (even tho I maintain
that in_softirq() && !in_hardirq() is as safe, as softirqs do
not nest).
Still returning the skbs to a CPU, tho, not to the NAPI instance.
I reckon we could create a small refcounted struct per NAPI instance
which would allow sockets and other users so hold a persisent
and safe reference. But that's a bigger change, and I get 90+%
recycling thru the cache with just these patches (for RR and
streaming tests with 100% CPU use it's almost 100%).
Some numbers for streaming test with 100% CPU use (from previous version,
but really they perform the same):

Recent patches to mlx5 mentioned a regression when moving from
driver local page pool to only using the generic page pool code.
Page pool has two recycling paths (1) direct one, which runs in
safe NAPI context (basically consumer context, so producing
can be lockless); and (2) via a ptr_ring, which takes a spin
lock because the freeing can happen from any CPU; producer
and consumer may run concurrently.
Since the page pool code was added, Eric introduced a revised version
of deferred skb freeing. TCP skbs are now usually returned to the CPU
which allocated them, and freed in softirq context. This places the
freeing (producing of pages back to the pool) enticingly close to
the allocation (consumer).
If we can prove that we're freeing in the same softirq context in which
the consumer NAPI will run - lockless use of the cache is perfectly fine,
no need for the lock.
Let drivers link the page pool to a NAPI instance. If the NAPI instance
is scheduled on the same CPU on which we're freeing - place the pages
in the direct cache.
With that and patched bnxt (XDP enabled to engage the page pool, sigh,
bnxt really needs page pool work :() I see a 2.6% perf boost with
a TCP stream test (app on a different physical core than softirq).
The CPU use of relevant functions decreases as expected:
page_pool_refill_alloc_cache 1.17% -> 0%
_raw_spin_lock 2.41% -> 0.98%
Only consider lockless path to be safe when NAPI is scheduled
- in practice this should cover majority if not all of steady state
workloads. It's usually the NAPI kicking in that causes the skb flush.
The main case we'll miss out on is when application runs on the same
CPU as NAPI. In that case we don't use the deferred skb free path.

We maintain a NAPI-local cache of skbs which is fed by napi_consume_skb().
Going forward we will also try to cache head and data pages.
Plumb the "are we in a normal NAPI context" information thru
deeper into the freeing path, up to skb_release_data() and
skb_free_head()/skb_pp_recycle(). The "not normal NAPI context"
comes from netpoll which passes budget of 0 to try to reap
the Tx completions but not perform any Rx.
Use "bool napi_safe" rather than bare "int budget",
the further we get from NAPI the more confusing the budget
argument may seem (particularly whether 0 or MAX is the
correct value to pass in when not in NAPI).

The handling of journalled data in ext4_zero_range() is incomplete. We
do not need to commit running transaction but we rather need to
checkpoint pages with journalled data. If we don't, journal tail can be
advanced beyond transaction containing the journalled data and if we
then crash before committing the transaction doing the zeroing we will
have inconsistent (too old) data in the file. Make sure file pages with
journalled data are properly checkpointed before removing them from the
page cache.

When journalling data we currently just walk over pages, journal those
that are marked for delayed dirtying (only pinned pages dirtied behing
our back these days) and checkpoint other dirty pages. Because some
pages may be part of running transaction the result is that after
filemap_write_and_wait() we are not guaranteed pages are stable on disk.
Thus places that want to flush current pagecache content need to jump
through hoops to make sure journalled data is not lost. This is
manageable in cases completely controlled by ext4 (such as extent
shifting operations or inode eviction) but it gets ugly for stuff like
fsverity. Furthermore it is rather error prone as people often do not
realize journalled data needs special handling.
So change ext4_writepages() to commit transaction with inode's data
before going through the writeback loop in WB_SYNC_ALL mode. As a result
filemap_write_and_wait() is now really getting pages to stable storage
and makes pagecache pages safe to reclaim. Consequently we can remove
the special handling of journalled data from several places in follow up
patches.
Note that this will make fsync(2) for journalled data more expensive as
we will end up not only committing the transaction we need but also
checkpointing the data (which we may have previously skipped if the data
was part of the running transaction). If we really cared, we would need
to introduce special VFS function for writing out & invalidating page
cache for a range, use ->launder_page callback to perform checkpointing,
and use it from all the places that need this functionality. But at this
point I'm not convinced the complexity is worth it.

With journalled data it can happen that checkpointing code will write
out page contents without clearing the page dirty bit. The logic in
ext4_page_nomap_can_writeout() then results in us never calling
mpage_submit_page() and thus clearing the dirty bit. Drop the
optimization with ext4_page_nomap_can_writeout() and just always call to
mpage_submit_page(). ext4_bio_write_page() knows when to redirty the
page and the additional clearing & setting of page dirty bit for ordered
mode writeout is not that expensive to jump through the hoops for it.

Currently we clear page dirty bit when we checkpoint some buffers from a
page with journalled data or when we perform delayed dirtying of a page
in ext4_writepages(). In a quest to simplify handling of journalled data
we want to keep page dirty as long as it has either buffers to
checkpoint or journalled dirty data. So make sure to keep page dirty in
ext4_writepages() if it still has journalled data attached to it.

Currently pages with journalled data written by write(2) or modified by
block zeroing during truncate(2) are not marked as dirty. They are
dirtied only once the transaction commits. This however makes writeback
code think inode has no pages to write and so ext4_writepages() is not
called to make pages with journalled data persistent. Mark pages with
journalled data dirty (similarly as it happens for writes through mmap)
so that writeback code knows about them and ext4_writepages() can do
what it needs to to the inode.

When invalidating buffers under the partial tail page,
jbd2_journal_invalidate_folio() returns -EBUSY if the buffer is part of
the committing transaction as we cannot safely modify buffer state.
However if the buffer is already invalidated (due to previous
invalidation attempts from ext4_wait_for_tail_page_commit()), there's
nothing to do and there's no point in returning -EBUSY. This fixes
occasional warnings from ext4_journalled_invalidate_folio() triggered by
generic/051 fstest when blocksize < pagesize.

When allocating a QP we allocate an RQ and an SQ, the RQ is stored first
in memory and followed by the SQ.
This allocation is not physically continiuos - it may span across different
physical pages. SW Steering code always writes in pairs: 1BB write + 1BB read,
or 2 continuous BBs of GTA WQE.
This lead to an issue where RQ allocation was 4x16 which is equal to 1 WQE BB,
causing 1 BB offset in the page and splitting the GTA WQE between different
physical pages.
The solution was to create the RQ with a even number of BBs and to have the
RQ aligned to a page.

Instead of using the write buffer for reading we will use a dedicated
buffer only for reading ICM memory.
Due to the new support for args, we can have a case with pending_wc
being odd number, and with reading into the same write buffer, it is
possible to overwrite next write on the same slot.
For example:
pending_wc is 17 so the buffer for write is:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
and we have requests as follows:
r wr wr wr wr wr wr wr wr
Now, the first read will be written into the last write because we use
the same buffer for read and write, before it was written to the HW and
we will have a wrong data in the ICM area.

It looks better to place this field in ring
structure. Also drop the repeated ring funcs definitions
if there's no difference except for vmhub field.
v2: rename the field to vm_hub like others (Le)
v3: apply the changes to new ip blocks (Hawking)
v4: fix vcn sw ring (Alex)
