1d666ab2da dt-bindings: input: Convert hid-over-i2c to DT schema
Convert the hid-over-i2c binding to DT schema format. The supplies should
probably be specific to a specific device, but it seems they are already
in use otherwise. 'wakeup-source' is added as it was not explicitly
documented.

There's a few warnings for undocumented properties 'vcc-supply' and
'reset-gpios'. Those remain as they probably should have a specific
compatible as well.

70d5ab5320 dt-bindings: nfc: marvell,nci: fix reset line polarity in examples
The reset line is supposed to be "active low" (it even says so in the
description), but examples incorrectly show it as "active high"
(likely because original examples use 0 which is technically "active
high" but in practice often "don't care" if the driver is using legacy
gpio API, as this one does).

The default value is true giving backwards compatibility. However, for

KUNIT_DEFAULT_ENABLED can be set to N requiring the tester to opt-in
by passing kunit.enable=1 to the kernel.

cbfecb927f fs: record I_DIRTY_TIME even if inode already has I_DIRTY_INODE
Currently the I_DIRTY_TIME will never get set if the inode already has
I_DIRTY_INODE with assumption that it supersedes I_DIRTY_TIME.  That's
true, however ext4 will only update the on-disk inode in
->dirty_inode(), not on actual writeback. As a result if the inode
already has I_DIRTY_INODE state by the time we get to
__mark_inode_dirty() only with I_DIRTY_TIME, the time was already filled
into on-disk inode and will not get updated until the next I_DIRTY_INODE
update, which might never come if we crash or get a power failure.

The problem can be reproduced on ext4 by running xfstest generic/622
with -o iversion mount option.

Fix it by allowing I_DIRTY_TIME to be set even if the inode already has
I_DIRTY_INODE. Also make sure that the case is properly handled in
writeback_single_inode() as well. Additionally changes in
xfs_fs_dirty_inode() was made to accommodate for I_DIRTY_TIME in flag.

Thanks Jan Kara for suggestions on how to make this work properly.

nlmsg_flags are full of historical baggage, inconsistencies and

of the ECHO flag (and while at it clarify the comment in the uAPI).
Handwave a little about the NEW request flags and how they make
sense on the surface but cater to really old paradigm before commands
were a thing.

I will add more notes on how to make use of ECHO and discouragement
for reuse of flags to the kernel-side documentation.

1cfd9d7e43 coding-style.rst: document BUG() and WARN() rules ("do not crash the kernel")
Linus notes [1] that the introduction of new code that uses VM_BUG_ON()
is just as bad as BUG_ON(), because it will crash the kernel on
distributions that enable CONFIG_DEBUG_VM (like Fedora):

    VM_BUG_ON() has the exact same semantics as BUG_ON. It is literally
    no different, the only difference is "we can make the code smaller
    because these are less important". [2]

This resulted in a more generic discussion about usage of BUG() and
friends. While there might be corner cases that still deserve a BUG_ON(),
most BUG_ON() cases should simply use WARN_ON_ONCE() and implement a
recovery path if reasonable:

    The only possible case where BUG_ON can validly be used is "I have
    some fundamental data corruption and cannot possibly return an
    error". [2]

As a very good approximation is the general rule:

    "absolutely no new BUG_ON() calls _ever_" [2]

... not even if something really shouldn't ever happen and is merely for
documenting that an invariant always has to hold. However, there are sill
exceptions where BUG_ON() may be used:

    If you have a "this is major internal corruption, there's no way we can
    continue", then BUG_ON() is appropriate. [3]

There is only one good BUG_ON():

    Now, that said, there is one very valid sub-form of BUG_ON():
    BUILD_BUG_ON() is absolutely 100% fine. [2]

While WARN will also crash the machine with panic_on_warn set, that's
exactly to be expected:

    So we have two very different cases: the "virtual machine with good
    logging where a dead machine is fine" - use 'panic_on_warn'. And
    the actual real hardware with real drivers, running real loads by
    users. [4]

The basic idea is that warnings will similarly get reported by users
and be found during testing. However, in contrast to a BUG(), there is a
way to actually influence the expected behavior (e.g., panic_on_warn)
and to eventually keep the machine alive to extract some debug info.

Ingo notes that not all WARN_ON_ONCE cases need recovery. If we don't ever
expect this code to trigger in any case, recovery code is not really
helpful.

    I'd prefer to keep all these warnings 'simple' - i.e. no attempted
    recovery & control flow, unless we ever expect these to trigger.
    [5]

There have been different rules floating around that were never properly
documented. Let's try to clarify.
