Some Qualcomm Bluetooth controllers, e.g., QCNFA765 with WCN6855
chip, send debug packets as ACL frames with header 0x2EDC.
The kernel misinterprets these as malformed ACL packets, causing
repeated errors:
Bluetooth: hci0: ACL packet for unknown connection handle 3804
This can occur hundreds of times per minute, greatly cluttering logs.
On my computer, I am observing approximately 7 messages per second
when streaming audio to a speaker.
For Qualcomm controllers exchanging over UART, hci_qca.c already
filters out these debug packets. This patch is for controllers
not going through UART, but USB.
This patch uses the classify_pkt_type callback to reclassify the
packets with handle 0x2EDC as HCI_DIAG_PKT before they reach the
HCI layer. This change is only applied to Qualcomm devices marked
as BTUSB_QCA_WCN6855.
Tested on: Thinkpad T14 gen2 (AMD) with QCNFA765 (0489:E0D0)

The UART-based H5 protocol supports CRC data integrity checks for
reliable packets. The host sets bit 5 in the configuration field of the
CONFIG link control message to indicate that CRC is supported. The
controller sets the same bit in the CONFIG RESPONSE message to indicate
that CRC may be used from then on.
Tested on a MangoPi MQ-Pro with a Realtek RTL8723DS Bluetooth controller
using the tip of the bluetooth-next tree.

Previously, h5_open() called h5_link_control() to send a SYNC message.
But h5_link_control() only enqueues the packet and requires the caller
to call hci_uart_tx_wakeup(). Thus, after H5_SYNC_TIMEOUT ran out
(100ms), h5_timed_event() would be called and, realizing that the state
was still H5_UNINITIALIZED, it would re-enqueue the SYNC and call
hci_uart_tx_wakeup(). Consequently, two SYNC packets would be sent and
initialization would unnecessarily wait for 100ms.
The naive solution of calling hci_uart_tx_wakeup() in h5_open() does not
work because it will only schedule tx work if the HCI_PROTO_READY bit is
set and hci_serdev only sets it after h5_open() returns. This patch
removes the extraneous SYNC being enqueued and makes h5_timed_event()
wake up on the next jiffy.

Support the platform Bluetooth to be reset by hardware pin,
when a Bluetooth exception occurs, attempt to reset the
Bluetooth module using the hardware reset pin, as this
method is generally more stable and reliable than a
software reset. If the hardware reset pin is not specified
in the device tree, fall back to the existing software
reset mechanism to ensure backward compatibility.

Convert the enetc driver to use the new .get_rx_ring_count
ethtool operation instead of implementing .get_rxnfc for handling
ETHTOOL_GRXRINGS command. This simplifies the code in two ways:
1. For enetc_get_rxnfc(): Remove the ETHTOOL_GRXRINGS case from the
switch statement while keeping other cases for classifier rules.
2. For enetc4_get_rxnfc(): Remove it completely and use
enetc_get_rxnfc() instead.
Now on, enetc_get_rx_ring_count() is the callback that returns the
number of RX rings for enetc driver.
Also, remove the documentation around enetc4_get_rxnfc(), which was not
matching what the function did(?!).

Add CPU caching to properties line in VM snapshot capture indicating
the BO caching properites. This is useful information for debug and
will help build a robust GPU hang replay tool.
The current format is:
[<vma address>]: <permissions>|<type>|mem_region=0x%x|pat_index=%d|cpu_caching=%d
Permissions has two options, either "read_only" or "read_write".
Type has three options, either "userptr", "null_sparse", or "bo".
Memory region is a bit mask of where the memory is located.
Pat index corresponds to the value setup upon VM bind.
CPU caching corresponds to the value of BO setup upon creation.
v2:
- Save off cpu_caching value rather than looking at BO (Carlos)
v4:
- Fix NULL ptr dereference (Carlos)

Pull vfs inode updates from Christian Brauner:
"Features:
- Hide inode->i_state behind accessors. Open-coded accesses prevent
asserting they are done correctly. One obvious aspect is locking,
but significantly more can be checked. For example it can be
detected when the code is clearing flags which are already missing,
or is setting flags when it is illegal (e.g., I_FREEING when
->i_count > 0)
- Provide accessors for ->i_state, converts all filesystems using
coccinelle and manual conversions (btrfs, ceph, smb, f2fs, gfs2,
overlayfs, nilfs2, xfs), and makes plain ->i_state access fail to
compile
- Rework I_NEW handling to operate without fences, simplifying the
code after the accessor infrastructure is in place
Cleanups:
- Move wait_on_inode() from writeback.h to fs.h
- Spell out fenced ->i_state accesses with explicit smp_wmb/smp_rmb
for clarity
- Cosmetic fixes to LRU handling
- Push list presence check into inode_io_list_del()
- Touch up predicts in __d_lookup_rcu()
- ocfs2: retire ocfs2_drop_inode() and I_WILL_FREE usage
- Assert on ->i_count in iput_final()
- Assert ->i_lock held in __iget()

- Add missing fences to I_NEW handling"

Pull misc vfs updates from Christian Brauner:
"Features:
- Cheaper MAY_EXEC handling for path lookup. This elides MAY_WRITE
permission checks during path lookup and adds the
IOP_FASTPERM_MAY_EXEC flag so filesystems like btrfs can avoid
expensive permission work.
- Hide dentry_cache behind runtime const machinery.
- Add German Maglione as virtiofs co-maintainer.
Cleanups:
- Tidy up and inline step_into() and walk_component() for improved
code generation.
- Re-enable IOCB_NOWAIT writes to files. This refactors file
timestamp update logic, fixing a layering bypass in btrfs when
updating timestamps on device files and improving FMODE_NOCMTIME
handling in VFS now that nfsd started using it.
- Path lookup optimizations extracting slowpaths into dedicated
routines and adding branch prediction hints for mntput_no_expire(),
fd_install(), lookup_slow(), and various other hot paths.
- Enable clang's -fms-extensions flag, requiring a JFS rename to
avoid conflicts.
- Remove spurious exports in fs/file_attr.c.
- Stop duplicating union pipe_index declaration. This depends on the
shared kbuild branch that brings in -fms-extensions support which
is merged into this branch.
- Use MD5 library instead of crypto_shash in ecryptfs.
- Use largest_zero_folio() in iomap_dio_zero().
- Replace simple_strtol/strtoul with kstrtoint/kstrtouint in init and
initrd code.
- Various typo fixes.
Fixes:
- Fix emergency sync for btrfs. Btrfs requires an explicit sync_fs()
call with wait == 1 to commit super blocks. The emergency sync path
never passed this, leaving btrfs data uncommitted during emergency
sync.
- Use local kmap in watch_queue's post_one_notification().
- Add hint prints in sb_set_blocksize() for LBS dependency on THP"

Drop the display dependency on intel_wakeref.h header. The contract in
the parent interface is that -ENOENT means there's no tracking. It
doesn't actually require us to use a shared macro for it. Duplicate the
macro in the few places that need this instead of inlining, primarily
for documentation reasons.
This allows us to remove the xe compat intel_wakeref.h header.
