6acd87d509 erofs/zmap.c: Fix incorrect offset calculation
Effective offset to add to length was being incorrectly calculated,
which resulted in iomap->length being set to 0, triggering a WARN_ON
in iomap_iter_done().

Fix that, and describe it in comments.

This was reported as a crash by syzbot under an issue about a warning
encountered in iomap_iter_done(), but unrelated to erofs.

fef4e61b0b ALSA: firewire-lib: extend tracepoints event including CYCLE_TIME of 1394 OHCI
A commit baa914cd81 ("firewire: add kernel API to access CYCLE_TIME
register") allow unit drivers to read CYCLE_TIME of 1394 OHCI controller.
The value expresses monotonic time with 42.195 Mhz resolution and wrapping
around every 128 seconds. The controller uses the time to govern
isochronous cycle.

This commit extends tracepoints event including the value so that event
parser can compute gap between current isochronous cycle and the latest
isochronous cycle in which packet is processed (in IR context) or scheduled
(in IT context). It loses backward compatibility to former format of the
tracepoints event.

Refactor rdma_bind_addr function so that it doesn't require that the

So now it will update the destination address internally only when it is

Which in turn results in a cleaner and more sensible call and error
handling flows for the functions that call it directly or indirectly.

453116a441 nvme-pci: add NVME_QUIRK_IDENTIFY_CNS quirk to Apple T2 controllers
This mirrors the quirk added to Apple Silicon controllers in apple.c.
These controllers do not support the Active NS ID List command and
behave identically to the SoC version judging by existing user

back to NVMe 1.0 behavior and disables the broken commands.

aa96d6aa75 nvme-apple: add NVME_QUIRK_IDENTIFY_CNS quirk to fix regression
From the get-go, this driver and the ANS syslog have been complaining
about namespace identification. In 6.2-rc1, commit 811f4de034 ("nvme:
avoid fallback to sequential scan due to transient issues") regressed
the driver by no longer allowing fallback to sequential namespace scans,
leaving us with no namespaces.

It turns out that the real problem is that this controller claiming
NVMe 1.1 compat is treating the CNS field as a binary field, as in NVMe
1.0. This already has a quirk, NVME_QUIRK_IDENTIFY_CNS, so set it for
the controller to fix all this nonsense (including other errors
triggered by other CNS commands).

creating an interface via netlink. This doesn't work for child PKEY
interfaces because the child interface uses the parent receive channels.

Although the child shares the parent's receive channels, the number of
rx queues is important for the channel_stats array: the parent's rx
channel index is used to access the child's channel_stats. So the array
has to be at least as large as the parent's rx queue size for the
counting to work correctly and to prevent out of bound accesses.

This patch checks for the mentioned scenario and returns an error when
trying to create the interface. The error is propagated to the user.

806a8df712 net/mlx5e: IPoIB, Block queue count configuration when sub interfaces are present
PKEY sub interfaces share the receive queues with the parent interface.
While setting the sub interface queue count is not supported, it is
currently possible to change the number of queues of the parent interface.
Thus we can end up with inconsistent queue sizes between the parent and its
sub interfaces.

This change disallows setting the queue count on the parent interface when
sub interfaces are present.

This is achieved by introducing an explicit reference to the parent netdev
in the mlx5i_priv of the child interface. An additional counter is also
required on the parent side to detect when sub interfaces are attached and
for proper cleanup.

The rtnl lock is taken during the ethtool op and the sub interface
ndo_init/uninit ops. There is no race here around counting the sub
interfaces, reading the sub interfaces and setting the number of
channels. The ASSERT_RTNL was added to document that.

da2e552b46 net/mlx5: Fix command stats access after free
Command may fail while driver is reloading and can't accept FW commands
till command interface is reinitialized. Such command failure is being
logged to command stats. This results in NULL pointer access as command
stats structure is being freed and reallocated during mlx5 devlink
reload (see kernel log below).

Fix it by making command stats statically allocated on driver probe.

5e72f3f1c5 net/mlx5e: TC, Keep mod hdr actions after mod hdr alloc
When offloading TC NIC rule which has mod_hdr action, the
mod_hdr actions list is freed upon mod_hdr allocation.

In the new format of handling multi table actions and CT in
particular, the mod_hdr actions list is still relevant when
setting the pre and post rules and therefore, freeing the list
may cause adding rules which don't set the FTE_ID.

Therefore, the mod_hdr actions list needs to be kept for the
pre/post flows as well and should be left for these handler to
be freed.

144ff5e03d Input: ipaq-micro-ts - use DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()
This driver never used the older SIMPLE_DEV_PM_OPS() but instead just
set two of the callbacks directly.  Skip that deprecated macro and go
straight to the new form that avoids the need for guarding or marking
callbacks __maybe_unused.

--
It is possible there is some subtle reason why only two of the
callbacks normally set by SIMPLE_DEV_PM_OPS() are set. As such,
this one needs some closer reading than many of the others.
