-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally.

2025-05-23traceevent/block: Add REQ_ATOMIC flag to block trace eventsRitesh Harjani (IBM)
Filesystems like XFS can implement atomic write I/O using either REQ_ATOMIC flag set in the bio or via CoW operation. It will be useful if we have a flag in trace events to distinguish between the two. This patch adds char 'U' (Untorn writes) to rwbs field of the trace events if REQ_ATOMIC flag is set in the bio. <W/ REQ_ATOMIC> ================= xfs_io-4238 [009] ..... 4148.126843: block_rq_issue: 259,0 WFSU 16384 () 768 + 32 none,0,0 [xfs_io] <idle>-0 [009] d.h1. 4148.129864: block_rq_complete: 259,0 WFSU () 768 + 32 none,0,0 [0] <W/O REQ_ATOMIC> =============== xfs_io-4237 [010] ..... 4143.325616: block_rq_issue: 259,0 WS 16384 () 768 + 32 none,0,0 [xfs_io] <idle>-0 [010] d.H1. 4143.329138: block_rq_complete: 259,0 WS () 768 + 32 none,0,0 [0] Signed-off-by: Ritesh Harjani (IBM) <ritesh.list@gmail.com> Reviewed-by: Ojaswin Mujoo <ojaswin@linux.ibm.com> Link: https://lore.kernel.org/r/44317cb2ec4588f6a2c1501a96684e6a1196e8ba.1747921498.git.ritesh.list@gmail.com Signed-off-by: Jens Axboe <axboe@kernel.dk>

2025-05-23iommu/vt-d: Restore context entry setup order for aliased devicesLu Baolu
Commit 2031c469f816 ("iommu/vt-d: Add support for static identity domain") changed the context entry setup during domain attachment from a set-and-check policy to a clear-and-reset approach. This inadvertently introduced a regression affecting PCI aliased devices behind PCIe-to-PCI bridges. Specifically, keyboard and touchpad stopped working on several Apple Macbooks with below messages: kernel: platform pxa2xx-spi.3: Adding to iommu group 20 kernel: input: Apple SPI Keyboard as /devices/pci0000:00/0000:00:1e.3/pxa2xx-spi.3/spi_master/spi2/spi-APP000D:00/input/input0 kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: applespi spi-APP000D:00: Error writing to device: 01 0e 00 00 kernel: DMAR: DRHD: handling fault status reg 3 kernel: DMAR: [DMA Read NO_PASID] Request device [00:1e.3] fault addr 0xffffa000 [fault reason 0x06] PTE Read access is not set kernel: DMAR: DRHD: handling fault status reg 3 kernel: applespi spi-APP000D:00: Error writing to device: 01 0e 00 00 Fix this by restoring the previous context setup order.
