2025-04-22MAINTAINERS: add HFS/HFS+ maintainersViacheslav Dubeyko
Both the hfs and hfsplus filesystem have been orphaned since at least 2014, i.e., over 10 years. However, HFS/HFS+ driver needs to stay for Debian Ports as otherwise we won't be able to boot PowerMacs using GRUB because GRUB won't be usable anymore on PowerMacs with HFS/HFS+ being removed from the kernel.

2025-04-22fs/buffer: split locking for pagecache lookupsDavidlohr Bueso
Callers of __find_get_block() may or may not allow for blocking semantics, and is currently assumed that it will not. Layout two paths based on this. The the private_lock scheme will continued to be used for atomic contexts. Otherwise take the folio lock instead, which protects the buffers, such as vs migration and try_to_free_buffers(). Per the "hack idea", the latter can alleviate contention on the private_lock for bdev mappings. For reasons of determinism and avoid making bugs hard to reproduce, the trylocking is not attempted. No change in semantics. All lookup users still take the spinlock.

2025-04-22dma-coherent: Warn if OF reserved memory is beyond current coherent DMA maskChen-Yu Tsai
When a reserved memory region described in the device tree is attached to a device, it is expected that the device's limitations are correctly included in that description. However, if the device driver failed to implement DMA address masking or addressing beyond the default 32 bits (on arm64), then bad things could happen because the DMA address was truncated, such as playing back audio with no actual audio coming out, or DMA overwriting random blocks of kernel memory. Check against the coherent DMA mask when the memory regions are attached to the device. Give a warning when the memory region can not be covered by the mask. A warning instead of a hard error was chosen, because it is possible that existing drivers could be working fine even if they forgot to extend the coherent DMA mask.

2025-04-22ima: process_measurement() needlessly takes inode_lock() on MAY_READFrederick Lawler
On IMA policy update, if a measure rule exists in the policy, IMA_MEASURE is set for ima_policy_flags which makes the violation_check variable always true. Coupled with a no-action on MAY_READ for a FILE_CHECK call, we're always taking the inode_lock(). This becomes a performance problem for extremely heavy read-only workloads. Therefore, prevent this only in the case there's no action to be taken.

xfs_zoned_need_gc makes use of mult_frac() to calculate the threshold for triggering the zoned garbage collector, but, turns out mult_frac() doesn't properly work with 64-bit data types and this caused build failures on some 32-bit architectures. Fix this by essentially open coding mult_frac() in a 64-bit friendly way. Notice we don't need to bother with counters underflow here because xfs_estimate_freecounter() will always return a positive value, as it leverages percpu_counter_read_positive to read such counters.

The function utilized PTR_ERR_OR_ZERO for error checking. However, this approach is inappropriate in this context because the respective functions do not return NULL; they return pointers that encode errors.

2025-04-22drm/amdgpu: Add queue id support to the user queue wait IOCTLArunpravin Paneer Selvam
Add queue id support to the user queue wait IOCTL drm_amdgpu_userq_wait structure. This is required to retrieve the wait user queue and maintain the fence driver references in it so that the user queue in the same context releases their reference to the fence drivers at some point before queue destruction. Otherwise, we would gather those references until we don't have any more space left and crash. v2: Modify the UAPI comment as per the mesa and libdrm UAPI comment.

2025-04-22drm/amd/display: Default IPS to RCG_IN_ACTIVE_IPS2_IN_OFFLeo Li
[Why] Recent findings show negligible power savings between IPS2 and RCG during static desktop. In fact, DCN related clocks are higher when IPS2 is enabled vs RCG. RCG_IN_ACTIVE is also the default policy for another OS supported by DC, and it has faster entry/exit. [How] Remove previous logic that checked for IPS2 support, and just default to `DMUB_IPS_RCG_IN_ACTIVE_IPS2_IN_OFF`.

2025-04-22drm/amd/display: Fix ACPI edid parsing on some Lenovo systemsMario Limonciello
[Why] The ACPI EDID in the BIOS of a Lenovo laptop includes 3 blocks, but dm_helpers_probe_acpi_edid() has a start that is 'char'. The 3rd block index starts after 255, so it can't be indexed properly. This leads to problems with the display when the EDID is parsed. [How] Change the variable type to 'short' so that larger values can be indexed.
