"This contains cleanups that fell out of the work from async directory
handling:

- Change kern_path_locked() and user_path_locked_at() to never return
a negative dentry. This simplifies the usability of these helpers
in various places

- Drop d_exact_alias() from the remaining place in NFS where it is
still used. This also allows us to drop the d_exact_alias() helper
completely

- Drop an unnecessary call to fh_update() from nfsd_create_locked()

- Change i_op->mkdir() to return a struct dentry

Change vfs_mkdir() to return a dentry provided by the filesystems
which is hashed and positive. This allows us to reduce the number
of cases where the resulting dentry is not positive to very few
cases. The code in these places becomes simpler and easier to
understand.

- Repack DENTRY_* and LOOKUP_* flags"

Merge patch series "Change inode_operations.mkdir to return struct dentry *"

NeilBrown <neilb@suse.de> says:

This revised series contains a few clean-ups as requested by various
people but no substantial changes.

I reviewed the mkdir functions in many (all?) filesystems and found a
few that use d_instantiate() on an unlocked inode (after
unlock_new_inode()) and also support export_operations. These could
potentially call d_instantiate() on a directory inode which is already
attached to a dentry, though making that happen would usually require
guessing the filehandle correctly. I haven't tried to address those
here, (this patch set doesn't make that situation any worse) but I may
in the future.

Change inode_operations.mkdir to return struct dentry *

Some filesystems, such as NFS, cifs, ceph, and fuse, do not have
complete control of sequencing on the actual filesystem (e.g. on a
different server) and may find that the inode created for a mkdir
request already exists in the icache and dcache by the time the mkdir
request returns. For example, if the filesystem is mounted twice the
directory could be visible on the other mount before it is on the
original mount, and a pair of name_to_handle_at(), open_by_handle_at()
calls could instantiate the directory inode with an IS_ROOT() dentry
before the first mkdir returns.

This means that the dentry passed to ->mkdir() may not be the one that
is associated with the inode after the ->mkdir() completes. Some
callers need to interact with the inode after the ->mkdir completes and
they currently need to perform a lookup in the (rare) case that the
dentry is no longer hashed.

This lookup-after-mkdir requires that the directory remains locked to
avoid races. Planned future patches to lock the dentry rather than the
directory will mean that this lookup cannot be performed atomically with
the mkdir.

To remove this barrier, this patch changes ->mkdir to return the
resulting dentry if it is different from the one passed in.
Possible returns are:
NULL - the directory was created and no other dentry was used
ERR_PTR() - an error occurred
non-NULL - this other dentry was spliced in

This patch only changes file-systems to return "ERR_PTR(err)" instead of
"err" or equivalent transformations. Subsequent patches will make
further changes to some file-systems to return a correct dentry.

Not all filesystems reliably result in a positive hashed dentry:

- NFS, cifs, hostfs will sometimes need to perform a lookup of
the name to get inode information. Races could result in this
returning something different. Note that this lookup is
non-atomic which is what we are trying to avoid. Placing the
lookup in filesystem code means it only happens when the filesystem
has no other option.
- kernfs and tracefs leave the dentry negative and the ->revalidate
operation ensures that lookup will be called to correctly populate
the dentry. This could be fixed but I don't think it is important
to any of the users of vfs_mkdir() which look at the dentry.

The recommendation to use
d_drop();d_splice_alias()
is ugly but fits with current practice. A planned future patch will
change this.

ASoC: Updates for v6.13

This release was mainly about new drivers, there's a very large batch of
new drivers and devices including quite a few from newer vendors which
is great to see. Other than the new drivers and the usual routine fixes
and enhancements the bulk of the work has been Morimoto-san's continuing
work on simplifiying APIs, plus a few other bits:

- More API simplifications from Morimoto-san.
- Renaming of the sh directory to Renesas to reflect the focus on other
architectures.
- Factoring out of some of the common code for Realtek devices.
- Support for Allwinner H616, AMD ACP 6.3 systems, AWInic AW88081,
Cirrus Logic CS32L84, Everest ES8328, Iron Devices SMA1307, Longsoon
I2S, NeoFidelity NTP8918 and NTP8835, Philips UDA1342, Qualcomm

i2c-host updates for v6.13, part 1

Major Improvements and Refactoring:

- All controllers using the 'remove_new' callback have been
reverted to use the 'remove' callback.

- Intel SCH controller underwent significant refactoring,
this brings love and a modern look to the driver.

- PIIX4 driver refactored to enable usage by other drivers
(e.g., AMD ASF).

- iMX/MXC improved message handling to reduce protocol overhead:
Refactored DMA/non-DMA read/write and bus polling mechanisms
to achieve this.

- ACPI documentation for PIIX4.

New Features:

- i2c-cadence added support for atomic transfers.
- Qualcomm CII added support for a 32MHz serial engine clock.

Deprecated Features:

- Dropped outdated support for AMD756 S4882 and NFORCE2 S4985. If
somebody misses this, Jean will rewrite support using the proper
i2c mux framework.

New Hardware Support:

- Added support for:
- Intel Panther Lake (new ID)
- AMD ASF (new driver)
- S32G2/S32G3 SoCs (new ID)
- Realtek RTL I2C Controller (new driver)
- HJMC01 DesignWare ACPI HID (new ID)
- PIC64GX to Microchip Core (new ID)
- Qualcomm SDM670 to Qualcomm CCI (new ID)
