2025-05-21fs/netfs: remove `netfs_io_request.ractl`Max Kellermann
Since this field is only used by netfs_prepare_read_iterator() when called by netfs_readahead(), we can simply pass it as parameter. This shrinks the struct from 576 to 568 bytes.

2025-05-21ALSA: qc_audio_offload: try to reduce address space confusionArnd Bergmann
uaudio_transfer_buffer_setup() allocates a buffer for the subs->dev device, and the returned address for the buffer is a CPU local virtual address that may or may not be in the linear mapping, as well as a DMA address token that is accessible by the USB device, and this in turn may or may not correspond to the physical address. The use in the driver however assumes that these addresses are the linear map and the CPU physical address, respectively. Both are nonportable here, but in the end only the virtual address gets used by converting it to a physical address that gets mapped into a second iommu. Make this more explicit by pulling the conversion out first and warning if it is not part of the linear map, and using the actual physical address to map into the iommu in place of the dma address that may already be iommu-mapped into the usb host.

2025-05-21ALSA: qc_audio_offload: avoid leaking xfer_buf allocationArnd Bergmann
The info->xfer_buf_cpu member is set to a NULL value because the allocation happens in a different function and is only assigned to the function argument but never passed back. Pass it by reference instead to have a handle that can actually be freed by the final usb_free_coherent() call.

2025-05-21ALSA: qc_audio_offload: rename dma/iova/va/cpu/phys variablesArnd Bergmann
While trying to understand a bug in the audio offload code, I had to spend extra time due to unfortunate nameing of local variables and struct members. Change these to more conventional names that reflect the actual usage: - pointers to the CPU virtual addresses of a dma buffer get a _cpu suffix to disambiguate them for MMIO virtual addresses - MMIO virtual addresses that are mapped explicitly through the IOMMU get a _iova suffix consistently, rather than a mix of iova and va. - DMA addresses (dma_addr_t) that are in a device address space (linear or IOMMU) get a _dma suffix in place of the _pa suffix. - CPU physical (phys_addr_t) addresses get a _pa suffix. There is still a mixup with dma addresses here that I address in another patch. No functional changes are intended here.

2025-05-21can: dev: add struct data_bittiming_params to group FD parametersVincent Mailhol
This is a preparation patch for the introduction of CAN XL. CAN FD and CAN XL uses similar bittiming parameters. Add one level of nesting for all the CAN FD parameters. Typically: priv->can.data_bittiming; becomes: priv->can.fd.data_bittiming; This way, the CAN XL equivalent (to be introduced later) would be: priv->can.xl.data_bittiming; Add the new struct data_bittiming_params which contains all the data bittiming parameters, including the TDC and the callback functions. This done, update all the CAN FD drivers to make use of the new layout.

Document support for the CAN-FD Interface on the RZ/G3E (R9A09G047) SoC, which supports up to six channels. The CAN-FD module on RZ/G3E is very similar to the one on both R-Car V4H and RZ/G2L, but differs in some hardware parameters: * No external clock, but instead has ram clock. * Support up to 6 channels. * 20 interrupts.

RZ/G3E SoC has 20 interrupts, 2 resets and 6 channels that need more branching with conditional schema. Simplify the conditional schema with if statements rather than the complex if-else statements to prepare for supporting RZ/G3E SoC.

Bring in the netfs API documentation updates which had been in the vfs-6.16.misc branch for most of this cycle. So don't needlessly rewrite the vfs-6.16.misc by dropping it from that branch and moving it to vfs-6.16.netfs. Simply merge vfs-6.16.misc into vfs-6.16.netfs.

2025-05-21nvmem: Remove unused nvmem cell table supportGeert Uytterhoeven
Board files are deprecated by DT, and the last user of nvmem_add_cell_table() was removed by commit 2af4fcc0d3574482 ("ARM: davinci: remove unused board support") in v6.3. Hence remove all support for nvmem cell tables, and update the documentation. Device drivers can still register a single cell using nvmem_add_one_cell() (which was not documented before).

2025-05-21kernfs: Relax constraint in draining guardMichal Koutný
The active reference lifecycle provides the break/unbreak mechanism but the active reference is not truly active after unbreak -- callers don't use it afterwards but it's important for proper pairing of kn->active counting. Assuming this mechanism is in place, the WARN check in kernfs_should_drain_open_files() is too sensitive -- it may transiently catch those (rightful) callers between kernfs_unbreak_active_protection() and kernfs_put_active() as found out by Chen Ridong: kernfs_remove_by_name_ns kernfs_get_active // active=1 __kernfs_remove // active=0x80000002 kernfs_drain ... wait_event //waiting (active == 0x80000001) kernfs_break_active_protection // active = 0x80000001 // continue kernfs_unbreak_active_protection // active = 0x80000002 ... kernfs_should_drain_open_files // warning occurs kernfs_put_active To avoid the false positives (mind panic_on_warn) remove the check altogether. (This is meant as quick fix, I think active reference break/unbreak may be simplified with larger rework.)
