On some TUXEDO platforms, a Samsung 990 Evo NVMe leads to a high power consumption in s2idle sleep (2-3 watts). This patch applies 'Force No Simple Suspend' quirk to achieve a sleep with a lower power consumption, typically around 0.5 watts. Signed-off-by:

If a drive is unable to create IO queues on the initial probe, a subsequent reset will need to allocate the tagset if IO queue creation is successful. Without this, blk_mq_update_nr_hw_queues will crash on a bad pointer due to the invalid tagset. Fixes: eac3ef26 ("nvme-pci: split the initial probe from the rest path") Reviewed-by:

The NVMe AER notification of a persistent internal error triggers a reset. The existing warning message just says "due to AER", which can be confused with the unrelated PCIe AER condition. Just say what the event was instead of the generic overloaded acronym. Reviewed-by:

Commit 4733b65d ("nvme: start keep-alive after admin queue setup") moves starting keep-alive from nvme_start_ctrl() into nvme_init_ctrl_finish(), but don't move stopping keep-alive into nvme_uninit_ctrl(), so keep-alive work can be started and keep pending after failing to start controller, finally use-after-free is triggered if nvme host driver is unloaded. This patch fixes kernel panic when running nvme/004 in case that connection failure is triggered, by moving stopping keep-alive into nvme_uninit_ctrl(). This way is reasonable because keep-alive is now started in nvme_init_ctrl_finish().

As reported in [0], we may get a hang when formatting a XFS FS on a RAID0 drive. Commit 73a768d5 ("block: factor out a blk_write_zeroes_limit helper") changed __blkdev_issue_write_zeroes() to read the max write zeroes value in the loop. This is not safe as max write zeroes may change in value. Specifically for the case of [0], the value goes to 0, and we get an infinite loop. Lift the limit reading out of the loop.

read_balance() will avoid reading from slow disks as much as possible, however, if valid data only lands in slow disks, and a new normal disk is still in recovery, unrecovered data can be read: raid1_read_request read_balance raid1_should_read_first -> return false choose_best_rdev -> normal disk is not recovered, return -1 choose_bb_rdev -> missing the checking of recovery, return the normal disk -> read unrecovered data Root cause is that the checking of recovery is missing in choose_bb_rdev(). Hence add such checking to fix the problem. Also fix similar problem in choose_slow_rdev().

Extent Space Efficient (ESE) or thin provisioned volumes need to be formatted on demand during usual IO processing. The dasd_ese_needs_format function checks for error codes that signal the non existence of a proper track format. The check for incorrect length is to imprecise since other error cases leading to transport of insufficient data also have this flag set. This might lead to data corruption in certain error cases for example during a storage server warmstart. Fix by removing the check for incorrect length and replacing by explicitly checking for invalid track format in transport mode. Also remove the check for file protected since this is not a valid ESE handling case.

This reverts commit bc792884 ("s390/dasd: Establish DMA alignment"). Quoting the original commit: linux-next commit bf8d0853 ("iomap: add support for dma aligned direct-io") changes the alignment requirement to come from the block device rather than the block size, and the default alignment requirement is 512-byte boundaries. Since DASD I/O has page alignments for IDAW/TIDAW requests, let's override this value to restore the expected behavior. I mentioned TIDAW, but that was wrong. TIDAWs have no distinct alignment requirement (per p. 15-70 of POPS SA22-7832-13): Unless otherwise specified, TIDAWs may designate a block of main storage on any boundary and length up to 4K bytes, provided the specified block does not cross a 4 K-byte boundary. IDAWs do, but the original commit neglected that while ECKD DASD are typically formatted in 4096-byte blocks, they don't HAVE to be. Formatting an ECKD volume with smaller blocks is permitted (dasdfmt -b xxx), and the problematic commit enforces alignment properties to such a device that will result in errors, such as: [test@host ~]# lsdasd -l a367 | grep blksz blksz: 512 [test@host ~]# mkfs.xfs -f /dev/disk/by-path/ccw-0.0.a367-part1 meta-data=/dev/dasdc1 isize=512 agcount=4, agsize=230075 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=1 = reflink=1 bigtime=1 inobtcount=1 nrext64=1 data = bsize=4096 blocks=920299, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=16384, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 error reading existing superblock: Invalid argument mkfs.xfs: pwrite failed: Invalid argument libxfs_bwrite: write failed on (unknown) bno 0x70565c/0x100, err=22 mkfs.xfs: Releasing dirty buffer to free list! found dirty buffer (bulk) on free list! mkfs.xfs: pwrite failed: Invalid argument ...snipped... The original commit omitted the FBA discipline for just this reason, but the formatted block size of the other disciplines was overlooked. The solution to all of this is to revert to the original behavior, such that the block size can be respected. There were two commits [1] that moved this code in the interim, so a straight git-revert is not possible, but the change is straightforward. But what of the original problem? That was manifested with a direct-io QEMU guest, where QEMU itself was changed a month or two later with commit 25474d90aa ("block: use the request length for iov alignment") such that the blamed kernel commit is unnecessary. [1] commit 0127a47f ("dasd: move queue setup to common code") commit fde07a4d ("dasd: use the atomic queue limits API") Fixes: bc792884 ("s390/dasd: Establish DMA alignment") Reviewed-by:

Pull interrupt subsystem updates from Thomas Gleixner: "Core: - Provide a new mechanism to create interrupt domains. The existing interfaces have already too many parameters and it's a pain to expand any of this for new required functionality. The new function takes a pointer to a data structure as argument. The data structure combines all existing parameters and allows for easy extension. The first extension for this is to handle the instantiation of generic interrupt chips at the core level and to allow drivers to provide extra init/exit callbacks. This is necessary to do the full interrupt chip initialization before the new domain is published, so that concurrent usage sites won't see a half initialized interrupt domain. Similar problems exist on teardown. This has turned out to be a real problem due to the deferred and parallel probing which was added in recent years. Handling this at the core level allows to remove quite some accrued boilerplate code in existing drivers and avoids horrible workarounds at the driver level. - The usual small improvements all over the place Drivers: - Add support for LAN966x OIC and RZ/Five SoC - Split the STM ExtI driver into a microcontroller and a SMP version to allow building the latter as a module for multi-platform kernels - Enable MSI support for Armada 370XP on platforms which do not support IPIs - The usual small fixes and enhancements all over the place" * tag 'irq-core-2024-07-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (59 commits) irqdomain: Fix the kernel-doc and plug it into Documentation genirq: Set IRQF_COND_ONESHOT in request_irq() irqchip/imx-irqsteer: Handle runtime power management correctly irqchip/gic-v3: Pass #redistributor-regions to gic_of_setup_kvm_info() irqchip/bcm2835: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND irqchip/gic-v4: Make sure a VPE is locked when VMAPP is issued irqchip/gic-v4: Substitute vmovp_lock for a per-VM lock irqchip/gic-v4: Always configure affinity on VPE activation Revert "irqchip/dw-apb-ictl: Support building as module" Revert "Loongarch: Support loongarch avec" arm64: Kconfig: Allow build irq-stm32mp-exti driver as module ARM: stm32: Allow build irq-stm32mp-exti driver as module irqchip/stm32mp-exti: Allow building as module irqchip/stm32mp-exti: Rename internal symbols irqchip/stm32-exti: Split MCU and MPU code arm64: Kconfig: Select STM32MP_EXTI on STM32 platforms ARM: stm32: Use different EXTI driver on ARMv7m and ARMv7a irqchip/stm32-exti: Add CONFIG_STM32MP_EXTI irqchip/dw-apb-ictl: Support building as module irqchip/riscv-aplic: Simplify the initialization code ... -
