785892fe88 ceph: cache layout in parent dir on first sync create
If a create is done, then typically we'll end up writing to the file
soon afterward. We don't want to wait for the reply before doing that
when doing an async create, so that means we need the layout for the
new file before we've gotten the response from the MDS.

All files created in a directory will initially inherit the same layout,
so copy off the requisite info from the first synchronous create in the
directory, and save it in a new i_cached_layout field. Zero out the
layout when we lose Dc caps in the dir.

d484648787 ceph: decode interval_sets for delegated inos
Starting in Octopus, the MDS will hand out caps that allow the client
to do asynchronous file creates under certain conditions. As part of
that, the MDS will delegate ranges of inode numbers to the client.

Add the infrastructure to decode these ranges, and stuff them into an
xarray for later consumption by the async creation code.

Because the xarray code currently only handles unsigned long indexes,
and those are 32-bits on 32-bit arches, we only enable the decoding when
running on a 64-bit arch.

2ccb45462a ceph: perform asynchronous unlink if we have sufficient caps
The MDS is getting a new lock-caching facility that will allow it
to cache the necessary locks to allow asynchronous directory operations.
Since the CEPH_CAP_FILE_* caps are currently unused on directories,
we can repurpose those bits for this purpose.

When performing an unlink, if we have Fx on the parent directory,
and CEPH_CAP_DIR_UNLINK (aka Fr), and we know that the dentry being
removed is the primary link, then then we can fire off an unlink
request immediately and don't need to wait on reply before returning.

In that situation, just fix up the dcache and link count and return
immediately after issuing the call to the MDS. This does mean that we
need to hold an extra reference to the inode being unlinked, and extra
references to the caps to avoid races. Those references are put and
error handling is done in the r_callback routine.

If the operation ends up failing, then set a writeback error on the
directory inode, and the inode itself that can be fetched later by
an fsync on the dir.

The behavior of dir caps is slightly different from caps on normal
files. Because these are just considered an optimization, if the
session is reconnected, we will not automatically reclaim them. They
are instead considered lost until we do another synchronous op in the
parent directory.

Async dirops are enabled via the "nowsync" mount option, which is
patterned after the xfs "wsync" mount option. For now, the default
is "wsync", but eventually we may flip that.

a25949b990 ceph: cap tracking for async directory operations
Track and correctly handle directory caps for asynchronous operations.
Add aliases for Frc caps that we now designate at Dcu caps (when dealing
with directories).

Unlike file caps, we don't reclaim these when the session goes away, and
instead preemptively release them. In-flight async dirops are instead
handled during reconnect phase. The client needs to re-do a synchronous
operation in order to re-get directory caps.

891f3f5a6a ceph: add infrastructure for waiting for async create to complete
When we issue an async create, we must ensure that any later on-the-wire
requests involving it wait for the create reply.

Expand i_ceph_flags to be an unsigned long, and add a new bit that
MDS requests can wait on. If the bit is set in the inode when sending
caps, then don't send it and just return that it has been delayed.

3bb48b4142 ceph: add flag to designate that a request is asynchronous
...and ensure that such requests are never queued. The MDS has need to
know that a request is asynchronous so add flags and proper
infrastructure for that.

Also, delegated inode numbers and directory caps are associated with the
session, so ensure that async requests are always transmitted on the
first attempt and are never queued to wait for session reestablishment.

If it does end up looking like we'll need to queue the request, then
have it return -EJUKEBOX so the caller can reattempt with a synchronous
request.

flushing caps once the create reply comes in.

1b0c3b9f91 ceph: re-org copy_file_range and fix some error paths
This patch re-organizes copy_file_range, trying to fix a few issues in the
error handling.  Here's the summary:

- Abort copy if initial do_splice_direct() returns fewer bytes than
  requested.

- Move the 'size' initialization (with i_size_read()) further down in the
  code, after the initial call to do_splice_direct().  This avoids issues
  with a possibly stale value if a manual copy is done.

- Move the object copy loop into a separate function.  This makes it
  easier to handle errors (e.g, dirtying caps and updating the MDS
  metadata if only some objects have been copied before an error has
  occurred).

- Added calls to ceph_oloc_destroy() to avoid leaking memory with src_oloc
  and dst_oloc

- After the object copy loop, the new file size to be reported to the MDS
  (if there's file size change) is now the actual file size, and not the
  size after an eventual extra manual copy.

- Added a few dout() to show the number of bytes copied in the two manual
  copies and in the object copy loop.

f682dc713c ceph: replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

07c264ab8e net/mlx5e: add mlx5e_rep_indr_setup_ft_cb support
Add mlx5e_rep_indr_setup_ft_cb to support indr block setup
in FT mode.
Both tc rules and flow table rules are of the same format,
It can re-use tc parsing for that, and move the flow table rules
to their steering domain(the specific chain_index), the indr
block offload in FT also follow this scenario.

and add flow_setup_cb_t callback parameters in order set the
specific callback for FT in next patch.

eswitch_offloads_chains.{c,h} were just introduced this kernel release
cycle, eswitch is in high development demand right now and many
features are planned to be added to it. eswitch deserves its own
directory and here we move these new files to there, in preparation for
upcoming eswitch features and new files.

6838a35a45 net/mlx5: Use a separate work queue for fib event handling
In VF lag mode when remove the bonding module without bring down the
bond device first, we could potentially have circular dependency when we
unload IB devices and also handle fib events:
1. The bond work starts first;
2. The "modprobe -rv bonding" process tries to release the bond device,
   with the "pernet_ops_rwsem" lock hold;
3. The bond work blocks in unregister_netdevice_notifier() and waits for
the lock because fib event came right before;
4. The kernel fib module tries to free all the fib entries by broadcasting
   the "FIB_EVENT_NH_DEL" event;
5. Upon the fib event this lag_mp module holds the fib lock and queue a
   fib work.
So:
   bond work -> modprobe task -> kernel fib module -> lag_mp -> bond work

Today we either reload IB devices in roce lag in nic mode or either handle
fib events in switchdev mode, but a new feature could change that we'll
need to reload IB devices also in switchdev mode so this is a future proof
fix as one may not notice this later.

d2923aa453 mfd: intel-lpss: Fix Intel Elkhart Lake LPSS I2C input clock
Intel Elkhart Lake LPSS I2C has 100 MHz input clock instead of 133 MHz
that was our preliminary information. This will result slower I2C bus
clock when driver calculates its timing parameters in case ACPI tables
don't provide them.

Slower I2C bus clock is allowed but let's fix this to match with
reality.

While at it, keep the same default I2C device properties as Intel
Broxton since it is not known do they need any update.
