"One more patch that we'd like to get to 5.12 before release.
It's changing where and how the superblock is stored in the zoned
mode. It is an on-disk format change but so far there are no
implications for users as the proper mkfs support hasn't been merged
and is waiting for the kernel side to settle.
Until now, the superblocks were derived from the zone index, but zone
size can differ per device. This is changed to be based on fixed
offset values, to make it independent of the device zone size.
The work on that got a bit delayed, we discussed the exact locations
to support potential device sizes and usecases. (Partially delayed
also due to my vacation.) Having that in the same release where the
zoned mode is declared usable is highly desired, there are userspace
projects that need to be updated to recognize the feature. Pushing
that to the next release would make things harder to test"

btrfs: zoned: move superblock logging zone location
Moves the location of the superblock logging zones. The new locations of
the logging zones are now determined based on fixed block addresses
instead of on fixed zone numbers.
The old placement method based on fixed zone numbers causes problems when
one needs to inspect a file system image without access to the drive zone
information. In such case, the super block locations cannot be reliably
determined as the zone size is unknown. By locating the superblock logging
zones using fixed addresses, we can scan a dumped file system image without
the zone information since a super block copy will always be present at or
after the fixed known locations.
Introduce the following three pairs of zones containing fixed offset
locations, regardless of the device zone size.
- primary superblock: offset 0B (and the following zone)
- first copy: offset 512G (and the following zone)
- Second copy: offset 4T (4096G, and the following zone)
If a logging zone is outside of the disk capacity, we do not record the
superblock copy.
The first copy position is much larger than for a non-zoned filesystem,
which is at 64M. This is to avoid overlapping with the log zones for
the primary superblock. This higher location is arbitrary but allows
supporting devices with very large zone sizes, plus some space around in
between.
Such large zone size is unrealistic and very unlikely to ever be seen in
real devices. Currently, SMR disks have a zone size of 256MB, and we are
expecting ZNS drives to be in the 1-4GB range, so this limit gives us
room to breathe. For now, we only allow zone sizes up to 8GB. The
maximum zone size that would still fit in the space is 256G.
The fixed location addresses are somewhat arbitrary, with the intent of
maintaining superblock reliability for smaller and larger devices, with
the preference for the latter. For this reason, there are two superblocks
under the first 1T. This should cover use cases for physical devices and
for emulated/device-mapper devices.
The superblock logging zones are reserved for superblock logging and
never used for data or metadata blocks. Note that we only reserve the
two zones per primary/copy actually used for superblock logging. We do
not reserve the ranges of zones possibly containing superblocks with the
largest supported zone size (0-16GB, 512G-528GB, 4096G-4112G).
The zones containing the fixed location offsets used to store
superblocks on a non-zoned volume are also reserved to avoid confusion.

the expected CPU's TLB is flushed and not another, in our case it really
is best-effort (see comments in kfence_protect_page()).
Avoid the warning by disabling preemption around flush_tlb_one_kernel().

ia64: fix user_stack_pointer() for ptrace()
ia64 has two stacks:
- memory stack (or stack), pointed at by by r12
- register backing store (register stack), pointed at by
ar.bsp/ar.bspstore with complications around dirty
register frame on CPU.
In [1] Dmitry noticed that PTRACE_GET_SYSCALL_INFO returns the register
stack instead memory stack.
The bug comes from the fact that user_stack_pointer() and
current_user_stack_pointer() don't return the same register:
ulong user_stack_pointer(struct pt_regs *regs) { return regs->ar_bspstore; }
#define current_user_stack_pointer() (current_pt_regs()->r12)
The change gets both back in sync.
I think ptrace(PTRACE_GET_SYSCALL_INFO) is the only affected user by
this bug on ia64.
The change fixes 'rt_sigreturn.gen.test' strace test where it was
observed initially.

Thus above forms ABBA deadlock. The same deadlock was mentioned in
upstream commit
28f5a8a7c033 ("ocfs2: should wait dio before inode lock
in ocfs2_setattr()"). It seems that that commit only removed the
cluster lock (the victim of above dead lock) from the ABBA deadlock
party.
End-user visible effects: Process hang in truncate -> ocfs2_setattr path
and other processes hang at ocfs2_dio_end_io_write path.
This is to fix the deadlock itself. It removes inode_lock() call from
dio completion path to remove the deadlock and add ip_alloc_sem lock in
setattr path to synchronize the inode modifications.

When we do coredump for user process signal, this may be an SIGBUS signal

recovery work is finished correctly, then the get_dump_page() will not
return the error page as its process pte is set invalid by
memory_failure().
But memory_failure() may fail, and the process's related pte may not be
correctly set invalid, for current code, we will return the poison page,
get it dumped, and then lead to system panic as its in kernel code.
So check the poison status in get_dump_page(), and if TRUE, return NULL.
There maybe other scenario that is also better to check the posion status

net: fix hangup on napi_disable for threaded napi
napi_disable() is subject to an hangup, when the threaded
mode is enabled and the napi is under heavy traffic.
If the relevant napi has been scheduled and the napi_disable()
kicks in before the next napi_threaded_wait() completes - so
that the latter quits due to the napi_disable_pending() condition,
the existing code leaves the NAPI_STATE_SCHED bit set and the
napi_disable() loop waiting for such bit will hang.
This patch addresses the issue by dropping the NAPI_STATE_DISABLE
bit test in napi_thread_wait(). The later napi_threaded_poll()
iteration will take care of clearing the NAPI_STATE_SCHED.
This also addresses a related problem reported by Jakub:
before this patch a napi_disable()/napi_enable() pair killed
the napi thread, effectively disabling the threaded mode.
On the patched kernel napi_disable() simply stops scheduling
the relevant thread.

- let the main napi_thread_poll() loop clear the SCHED bit

vdpa/mlx5: Fix suspend/resume index restoration
When we suspend the VM, the VDPA interface will be reset. When the VM is
resumed again, clear_virtqueues() will clear the available and used
indices resulting in hardware virqtqueue objects becoming out of sync.
We can avoid this function alltogether since qemu will clear them if
required, e.g. when the VM went through a reboot.
Moreover, since the hw available and used indices should always be
identical on query and should be restored to the same value same value
for virtqueues that complete in order, we set the single value provided
by set_vq_state(). In get_vq_state() we return the value of hardware

USB: cdc-acm: fix TIOCGSERIAL implementation
TIOCSSERIAL is a horrid, underspecified, legacy interface which for most
serial devices is only useful for setting the close_delay and
closing_wait parameters.
The xmit_fifo_size parameter could be used to set the hardware transmit
fifo size of a legacy UART when it could not be detected, but the
interface is limited to eight bits and should be left unset when it is
not used.
Similarly, baud_base could be used to set the UART base clock when it
could not be detected, but might as well be left unset when it is not
known (which is the case for CDC).
Fix the cdc-acm TIOCGSERIAL implementation by dropping its custom
interpretation of the unused xmit_fifo_size and baud_base fields, which
overflowed the former with the URB buffer size and set the latter to the
current line speed. Also return the port line number, which is the only
other value used besides the close parameters.

This reverts commit
b401f8c4f492cbf74f3f59c9141e5be3071071bb.
The offending commit claimed that trying to set the values reported back
by TIOCGSERIAL as a regular user could result in an -EPERM error when HZ
is 250, but that was never the case.
With HZ=250, the default 0.5 second value of close_delay is converted to
125 jiffies when set and is converted back to 50 centiseconds by
TIOCGSERIAL as expected (not 12 cs as was claimed, even if that was the
case before an earlier fix).
Comparing the internal current and new jiffies values is just fine to
determine if the value is about to change so drop the bogus workaround
(which was also backported to stable).
For completeness: With different default values for these parameters or
with a HZ value not divisible by two, the lack of rounding when setting
the default values in tty_port_init() could result in an -EPERM being
returned, but this is hardly something we need to worry about.

an "altmodes" child fwnode on port->dev with this "altmodes" fwnode having
child fwnodes itself with each child containing 2 integer properties:
1. A "svid" property, which sets the id of the altmode, e.g. displayport
altmode has a svid of 0xff01.
2. A "vdo" property, typically used as a bitmask describing the
capabilities of the altmode, the bits in the vdo are specified in the
