Calling fd_install() makes a file reachable for userland, including the
possibility to close the file descriptor, which leads to calling its
'release' hook. If that happens before the code had a chance to bump the
reference of the newly created task struct, the release callback will
call put_task_struct() too early, leading to the premature destruction
of the kernel thread.
Avoid that race by calling fd_install() later, after all the setup is
done.

This code prints the wrong variable in the warning message. It should
print "i" instead of "info->offset". On the first iteration "info" is
uninitialized leading to a crash and on subsequent iterations it prints
the previous offset instead of the current one.

Before commit 7108b80a54 ("hwmon/coretemp: Handle large core ID
value"), there is a fixed mapping between
1. cpu_core_id
2. the index in pdata->core_data[] array
3. the sysfs attr name, aka "tempX_"
The later two always equal cpu_core_id + 2.
After the commit, pdata->core_data[] index is got from ida so that it
can handle sparse core ids and support more cores within a package.
However, the commit erroneously maps the sysfs attr name to
pdata->core_data[] index instead of cpu_core_id + 2.
As a result, the code is not aligned with the comments, and brings user
visible changes in hwmon sysfs on systems with sparse core id.
For example, before commit 7108b80a54 ("hwmon/coretemp: Handle large
core ID value"),
/sys/class/hwmon/hwmon2/temp2_label:Core 0
/sys/class/hwmon/hwmon2/temp3_label:Core 1
/sys/class/hwmon/hwmon2/temp4_label:Core 2
/sys/class/hwmon/hwmon2/temp5_label:Core 3
/sys/class/hwmon/hwmon2/temp6_label:Core 4
/sys/class/hwmon/hwmon3/temp10_label:Core 8
/sys/class/hwmon/hwmon3/temp11_label:Core 9
after commit,
/sys/class/hwmon/hwmon2/temp2_label:Core 0
/sys/class/hwmon/hwmon2/temp3_label:Core 1
/sys/class/hwmon/hwmon2/temp4_label:Core 2
/sys/class/hwmon/hwmon2/temp5_label:Core 3
/sys/class/hwmon/hwmon2/temp6_label:Core 4
/sys/class/hwmon/hwmon2/temp7_label:Core 8
/sys/class/hwmon/hwmon2/temp8_label:Core 9
Restore the previous behavior and rework the code, comments and variable
names to avoid future confusions.

If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER
handler cannot perform VF register successfully as the register call
is received before netvsc_probe is finished. This is because we
register register_netdevice_notifier() very early( even before
vmbus_driver_register()).
To fix this, we try to register each such matching VF( if it is visible
as a netdevice) at the end of netvsc_probe.

CPER events don't have UUIDs. Therefore UUIDs were removed from the
records passed to trace events and replaced with hard coded values.
As pointed out by Jonathan, the new defines for the UUIDs present a more
efficient way to assign UUID in trace records.[1]
Replace memcpy's with the use of static data.

CXL events were rerouted though the CXL subsystem for additional
processing. However, when that work was done it was missed that
cper_estatus_print_section() continued with a generic error message
which is confusing.
Teach CPER print code to ignore printing details of some section types.
Assign the CXL event GUIDs to this set to prevent confusing unknown
prints.

For XDP_TX action xdp_buff is converted to xdp_frame. The conversion is
done by xdp_convert_buff_to_frame(). The memory type of the resulting
xdp_frame depends on the memory type of the xdp_buff. For page pool
based xdp_buff it produces xdp_frame with memory type
MEM_TYPE_PAGE_POOL. For zero copy XSK pool based xdp_buff it produces
xdp_frame with memory type MEM_TYPE_PAGE_ORDER0.
tsnep_xdp_xmit_back() is not prepared for that and uses always the page
pool buffer type TSNEP_TX_TYPE_XDP_TX. This leads to invalid mappings
and the transmission of undefined data.
Improve tsnep_xdp_xmit_back() to use the generic buffer type
TSNEP_TX_TYPE_XDP_NDO for zero copy XDP_TX.

Using hard-coded constant timeout to wait for some expected
event is deemed to fail sooner or later, especially in slow
env.
Our CI has spotted another of such race:
# TEST: ipv6: cleanup of cached exceptions - nexthop objects [FAIL]
# can't delete veth device in a timely manner, PMTU dst likely leaked
Replace the crude sleep with a loop looking for the expected condition
at low interval for a much longer range.

The pmtu.sh test uses a few TCP listener in a problematic way:
It hard-codes a constant timeout to wait for the listener starting-up
in background. That introduces unneeded latency and on very slow and
busy host it can fail.
Additionally the test starts again the same listener in the same
namespace on the same port, just after the previous connection
completed. Fast host can attempt starting the new server before the
old one really closed the socket.
Address the issues using the wait_local_port_listen helper and
explicitly waiting for the background listener process exit.

The udpgro_fwd.sh self-tests are somewhat unstable. There are
a few timing constraints the we struggle to meet on very slow

Instead of skipping the whole tests in such envs, increase the

timeouts, avoid resetting the counters every second and finally
disable reduce the background traffic noise.

- Fix the return code for ring_buffer_poll_wait()
It was returing a -EINVAL instead of EPOLLERR.
- Zero out the tracefs_inode so that all fields are initialized.
The ti->private could have had stale data, but instead of
just initializing it to NULL, clear out the entire structure
when it is allocated.
- Fix a crash in timerlat
The hrtimer was initialized at read and not open, but is
canceled at close. If the file was opened and never read
the close will pass a NULL pointer to hrtime_cancel().
- Rewrite of eventfs.
Linus wrote a patch series to remove the dentry references in the
eventfs_inode and to use ref counting and more of proper VFS
interfaces to make it work.
- Add warning to put_ei() if ei is not set to free. That means
something is about to free it when it shouldn't.
- Restructure the eventfs_inode to make it more compact, and remove
the unused llist field.
- Remove the fsnotify*() funtions for when the inodes were being created
in the lookup code. It doesn't make sense to notify about creation
just because something is being looked up.
- The inode hard link count was not accurate. It was being updated
when a file was looked up. The inodes of directories were updating
their parent inode hard link count every time the inode was created.
That means if memory reclaim cleaned a stale directory inode and
the inode was lookup up again, it would increment the parent inode
again as well. Al Viro said to just have all eventfs directories
have a hard link count of 1. That tells user space not to trust it.

ahci: Extend ASM1061 43-bit DMA address quirk to other ASM106x parts
Another Fujitsu-related patch.
In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.
i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:3092) not working at all.
So this notebook uses a hid-over-i2c touchpad which is managed by the
i2c_designware input driver. Since you can't find a PS/2 mouse port on this
computer and you can't connect a PS/2 mouse to it even with an official
port replicator I think it's safe to not use the PS/2 mouse port at all.

Merge tag 'io_uring-6.8-2024-02-01' of git://git.kernel.dk/linux
Pull io_uring fixes from Jens Axboe:
- Fix for missing retry for read multishot.
If we trigger the execution of it and there's more than one buffer to
be read, then we don't always read more than the first one. As it's
edge triggered, this can lead to stalls.
- Limit inline receive multishot retries for fairness reasons.
If we have a very bursty socket receiving data, we still need to
ensure we process other requests as well. This is really two minor
cleanups, then adding a way for poll reissue to trigger a requeue,
and then finally having multishot receive utilize that.
- Fix for a weird corner case for non-multishot receive with
MSG_WAITALL, using provided buffers, and setting the length to
zero (to let the buffer dictate the receive size).
* tag 'io_uring-6.8-2024-02-01' of git://git.kernel.dk/linux:
