It's possible for the VFS to completely forget about an inode, but for
it to still be sitting on the cap release queue. If the MDS sends the
client a cap message for such an inode, it just ignores it today, which
can lead to a stall of up to 5s until the cap release queue is flushed.
If we get a cap message for an inode that can't be located, then go
ahead and flush the cap release queue.

Add memory info of the GCW Zero in its devicetree. The bootloader

it doesn't hurt to have it in devicetree. It allows the kernel to boot

OSD client should ignore cache/overlay flag if got redirect reply.
Otherwise, the client hangs when the cache tier is in forward mode.
[ idryomov: Redirects are effectively deprecated and no longer
used or tested. The original tiering modes based on redirects
are inherently flawed because redirects can race and reorder,
potentially resulting in data corruption. The new proxy and
readproxy tiering modes should be used instead of forward and
readforward. Still marking for stable as obviously correct,
though. ]

Back with commit c8c240e284b3 (cfg80211: reg: remove support for
built-in regdb, 2015-10-15), support for using CFG80211_INTERNAL_REGDB
was removed in favor of loading the regulatory database as firmware
file. The documentation of CFG80211_CRDA_SUPPORT was not adjusted,
though, which is why it still mentions mentions the old way of loading

As discussed with Mathy almost two years ago in
http://lore.kernel.org/r/20180806224857.14853-1-Mathy.Vanhoef@cs.kuleuven.be
we should let userspace process SA-QUERY frames if it
wants to, so that it can handle OCV (operating channel
validation) which mac80211 doesn't know how to.
Evidently I had been expecting Mathy to (re)send such a
patch, but he never did, perhaps expecting me to do it
after our discussion.
In any case, this came up now with OCV getting more
attention, so move the code around as discussed there
to let userspace handle it, and do it properly.

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]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

If the driver advertises NL80211_EXT_FEATURE_SCAN_FREQ_KHZ
userspace can omit NL80211_ATTR_SCAN_FREQUENCIES in favor
of an NL80211_ATTR_SCAN_FREQ_KHZ. To get scan results in
KHz userspace must also set the
NL80211_SCAN_FLAG_FREQ_KHZ.

cfg80211 recently gained the ability to understand a
frequency offset component in KHz. Expose this in nl80211
through the new attributes NL80211_ATTR_WIPHY_FREQ_OFFSET,
NL80211_FREQUENCY_ATTR_OFFSET,
NL80211_ATTR_CENTER_FREQ1_OFFSET, and
NL80211_BSS_FREQUENCY_OFFSET.
These add support to send and receive a KHz offset
component with the following NL80211 commands:
- NL80211_CMD_FRAME
- NL80211_CMD_GET_SCAN
- NL80211_CMD_AUTHENTICATE
- NL80211_CMD_ASSOCIATE
- NL80211_CMD_CONNECT
Along with any other command which takes a chandef, ie:
- NL80211_CMD_SET_CHANNEL
- NL80211_CMD_SET_WIPHY
- NL80211_CMD_START_AP
- NL80211_CMD_RADAR_DETECT
- NL80211_CMD_NOTIFY_RADAR
- NL80211_CMD_CHANNEL_SWITCH
- NL80211_JOIN_IBSS
- NL80211_CMD_REMAIN_ON_CHANNEL
- NL80211_CMD_JOIN_OCB
- NL80211_CMD_JOIN_MESH
- NL80211_CMD_TDLS_CHANNEL_SWITCH
If the driver advertises a band containing channels with
frequency offset, it must also verify support for
frequency offset channels in its cfg80211 ops, or return
an error.

Drivers may wish to report the RX frequency in units of
KHz. Provide cfg80211_rx_mgmt_khz() and wrap it with
cfg80211_rx_mgmt() so exisiting drivers which can't report
KHz anyway don't need to change. Add a similar wrapper for
cfg80211_report_obss_beacon() so the frequency units stay
somewhat consistent.

Current rule for applying TID configuration for specific peer looks overly
complicated. No need to reject new TID configuration when override flag is
specified. Another call with the same TID configuration, but without
override flag, allows to apply new configuration anyway.
Use the same approach as for the 'all peers' case: if override flag is
specified, then reset existing TID configuration and immediately
apply a new one.

Raw PHY TDR data
Some ethernet PHYs allow access to raw TDR data in addition to summary
diagnostics information. Add support for retrieving this data via
netlink ethtool. The basic structure in the core is the same as for
normal phy diagnostics, the PHY driver simply uses different helpers
to fill the netlink message with different data.
There is a graphical tool under development, as well a ethtool(1)
which can dump the data as text and JSON.
A patched ethtool(1) can be found in
https://github.com/lunn/ethtool.git feature/cable-test-v5

Fixed a ton of minor checkpatch errors/warnings and remove version
printing at module init/when device is found and use MODULE_VERSION
instead. Also modifying the RTL8029 PCI string to include the compatible
RTL8029AS nic.
The only mayor issue remaining is the missing SPDX tag, but since the
exact version of the GPL is not stated anywhere inside the file, its
impossible to add such a tag at the moment.
But maybe it is possible, since 8390.h states Donald Becker's 8390
drivers are licensed under GPL 2.2 only (= GPL-2.0-only ?).

Ignore loopback-originatig packets soon enough and don't try to process L2
header where it doesn't exist. The very similar br_handle_frame() in bridge
code performs exactly the same check.
This is an example of such ICMPv6 packet:

The Lenovo Thinkpad T470s I own has a different touchpad with "LEN007a"
instead of the already included PNP ID "LEN006c". However, my touchpad
seems to work well without any problems using RMI. So this patch adds the
other PNP ID.

Gigabyte TRX40 Aorus Master is equipped with two USB-audio devices,
a Realtek ALC1220-VB codec (USB ID 0414:a001) and an ESS SABRE9218 DAC
(USB ID 0414:a000). The latter serves solely for the headphone output
on the front panel while the former serves for the rest I/Os (mostly
for the I/Os in the rear panel but also including the front mic).
Both chips do work more or less with the unmodified USB-audio driver,
but there are a few glitches. The ALC1220-VB returns an error for an
inquiry to some jacks, as already seen on other TRX40-based mobos.
However this machine has a slightly incompatible configuration, hence
the existing mapping cannot be used as is.
Meanwhile the ESS chip seems working without any quirk. But since
both audio devices don't provide any specific names, both cards appear
as "USB-Audio", and it's quite confusing for users.
This patch is an attempt to overcome those issues:
- The specific mapping table for ALC1220-VB is provided, reducing the
non-working nodes and renaming the badly chosen controls.
The connector map isn't needed here unlike other TRX40 quirks.
- For both USB IDs (0414:a000 and 0414:a001), provide specific card
name strings, so that user-space can identify more easily; and more
importantly, UCM profile can be applied to each.

A static checker reported the following issue:
drivers/scsi/lpfc/lpfc_nvmet.c:1366 lpfc_nvmet_ls_abort()
warn: 'ret' can be either negative or positive
The comment indicates a non-zero value indicates error in the
form of -Exxx, but the code is returning "1".
Fix the code to return -EINVAL to be compliant to comment.

The axchg structure is a structure allocated early in the
lpfc_nvme_unsol_ls_handler() to represent the newly received exchange.
Upon error, the out_fail path in the routine unconditionally frees the
pointer, yet subsequently passes the pointer to the abort routine.
Additionally, the abort routine, lpfc_nvme_unsol_ls_issue_abort(), also
has a failure path that will attempt to delete the pointer on error.
Fix these errors by:
- Removing the unconditional free so that it stays valid if passed
to the abort routine.
- Revise the abort routine to not free the pointer. Instead, return
a success/failure status. Note: if success, the later completion of
the abort frees the structure.
- Back in the unsol_ls_handler() error path, if the abort routine was
skipped (thus no possible reference) or the abort routine returned
error, free the pointer.
