2024-11-11nvmet: implement rotational media information logKeith Busch
Most of the information is stubbed. Supporting these commands is a requirement for supporting rotational media. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Keith Busch <kbusch@kernel.org>
2024-11-11nvmet: implement endurance groupsKeith Busch
Most of the returned information is just stubbed data. The target must support these in order to report rotational media. Since this driver doesn't know any better, each namespace is its own endurance group with the engid value matching the nsid.

2024-11-11nvmet: support reservation featureGuixin Liu
This patch implements the reservation feature, including: 1. reservation register(register, unregister and replace). 2. reservation acquire(acquire, preempt, preempt and abort). 3. reservation release(release and clear). 4. reservation report. 5. set feature and get feature of reservation notify mask. 6. get log page of reservation event. Not supported: 1. persistent reservation through power loss. Test cases: Use nvme-cli and fio to test all implemented sub features: 1. use nvme resv-register to register host a registrant or unregister or replace a new key. 2. use nvme resv-acquire to set host to the holder, and use fio to send read and write io in all reservation type. And also test preempt and "preempt and abort". 3. use nvme resv-report to show all registrants and reservation status. 4. use nvme resv-release to release all registrants. 5. use nvme get-log to get events generated by the preceding operations. In addition, make reservation configurable, one can set ns to support reservation before enable ns. The default of resv_enable is false.

2024-11-11block: pre-calculate max_zone_append_sectorsChristoph Hellwig
max_zone_append_sectors differs from all other queue limits in that the final value used is not stored in the queue_limits but needs to be obtained using queue_limits_max_zone_append_sectors helper. This not only adds (tiny) extra overhead to the I/O path, but also can be easily forgotten in file system code. Add a new max_hw_zone_append_sectors value to queue_limits which is set by the driver, and calculate max_zone_append_sectors from that and the other inputs in blk_validate_zoned_limits, similar to how max_sectors is calculated to fix this.

2024-11-11dm-cache: fix warnings about duplicate slab cachesMikulas Patocka
The commit 4c39529663b9 adds a warning about duplicate cache names if CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-cache code. The dm-cache code allocates a slab cache for each device. This commit changes it to allocate just one slab cache in the module init function.

2024-11-11dm-bufio: fix warnings about duplicate slab cachesMikulas Patocka
The commit 4c39529663b9 adds a warning about duplicate cache names if CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-bufio code. The dm-bufio code allocates a slab cache with each client. It is not possible to preallocate the caches in the module init function because the size of auxiliary per-buffer data is not known at this point. So, this commit changes dm-bufio so that it appends a unique atomic value to the cache name, to avoid the warnings.

2024-11-11ublk: fix ublk_ch_mmap() for 64K page sizeMing Lei
In ublk_ch_mmap(), queue id is calculated in the following way: (vma->vm_pgoff << PAGE_SHIFT) / `max_cmd_buf_size` 'max_cmd_buf_size' is equal to `UBLK_MAX_QUEUE_DEPTH * sizeof(struct ublksrv_io_desc)` and UBLK_MAX_QUEUE_DEPTH is 4096 and part of UAPI, so 'max_cmd_buf_size' is always page aligned in 4K page size kernel. However, it isn't true in 64K page size kernel. Fixes the issue by always rounding up 'max_cmd_buf_size' with PAGE_SIZE.

2024-11-11cpufreq: intel_pstate: Rearrange locking in hybrid_init_cpu_capacity_scaling()Rafael J. Wysocki
Notice that hybrid_init_cpu_capacity_scaling() only needs to hold hybrid_capacity_lock around __hybrid_init_cpu_capacity_scaling() calls, so introduce a "locked" wrapper around the latter and call it from the former. This allows to drop a local variable and a label that are not needed any more. Also, rename __hybrid_init_cpu_capacity_scaling() to __hybrid_refresh_cpu_capacity_scaling() for consistency. Interestingly enough, this fixes a locking issue introduced by commit 929ebc93ccaa ("cpufreq: intel_pstate: Set asymmetric CPU capacity on hybrid systems") that put an arch_enable_hybrid_capacity_scale() call under hybrid_capacity_lock, which was a mistake because the latter is acquired in CPU hotplug paths and so it cannot be held around cpus_read_lock() calls.

2024-11-09s390/dasd: fix redundant /proc/dasd* entries removalMiroslav Franc
In case of an early failure in dasd_init, dasd_proc_init is never called and /proc/dasd* files are never created. That can happen, for example, if an incompatible or incorrect argument is provided to the dasd_mod.dasd= kernel parameter. However, the attempted removal of /proc/dasd* files causes 8 warnings and backtraces in this case. 4 on the error path within dasd_init and 4 when the dasd module is unloaded. Notice the "removing permanent /proc entry 'devices'" message that is caused by the dasd_proc_exit function trying to remove /proc/devices instead of /proc/dasd/devices since dasd_proc_root_entry is NULL and /proc/devices is indeed permanent.

2024-11-08i2c: designware: do not hold SCL low when I2C_DYNAMIC_TAR_UPDATE is not setLiu Peibao
When the Tx FIFO is empty and the last command has no STOP bit set, the master holds SCL low. If I2C_DYNAMIC_TAR_UPDATE is not set, BIT(13) MST_ON_HOLD of IC_RAW_INTR_STAT is not enabled, causing the __i2c_dw_disable() timeout. This is quite similar to commit 2409205acd3c ("i2c: designware: fix __i2c_dw_disable() in case master is holding SCL low"). Also check BIT(7) MST_HOLD_TX_FIFO_EMPTY in IC_STATUS, which is available when IC_STAT_FOR_CLK_STRETCH is set.

Both of the Marks have been working on this for a couple of weeks and we've ended up in a position where SVE is solid but SME still has enough pending issues that the most pragmatic solution for the release and stable backports is to disable the feature. Yes, it's a shame, but the hardware is rare as hen's teeth at the moment and we're better off getting back to a known good state before fixing it all properly. We're also improving the selftests for 6.13 to help avoid merging broken code in the future. Anyway, the good news is that we're removing a lot more code than we're adding. Summary: - Fix handling of SVE traps from userspace on preemptible kernels when converting the saved floating point state into SVE state. - Remove broken support for the SMCCCv1.3 "SVE discard hint" optimisation. - Disable SME support, as the current support code suffers from numerous issues around signal delivery, ptrace access and context-switch which can lead to user-visible corruption of the register state" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Kconfig: Make SME depend on BROKEN for now arm64: smccc: Remove broken support for SMCCCv1.3 SVE discard hint arm64/sve: Discard stale CPU state when handling SVE traps

2024-11-07md/raid5: Wait sync io to finish before changing group cntXiao Ni
One customer reports a bug: raid5 is hung when changing thread cnt while resync is running. The stripes are all in conf->handle_list and new threads can't handle them. Commit b39f35ebe86d ("md: don't quiesce in mddev_suspend()") removes pers->quiesce from mddev_suspend/resume. Before this patch, mddev_suspend needs to wait for all ios including sync io to finish. Now it's used to only wait normal io. Fix this by calling raid5_quiesce from raid5_store_group_thread_cnt directly to wait all sync requests to finish before changing the group cnt.

2024-11-07vdpa/mlx5: Fix error path during device addDragos Tatulea
In the error recovery path of mlx5_vdpa_dev_add(), the cleanup is executed and at the end put_device() is called which ends up calling mlx5_vdpa_free(). This function will execute the same cleanup all over again. Most resources support being cleaned up twice, but the recent mlx5_vdpa_destroy_mr_resources() doesn't. This change drops the explicit cleanup from within the mlx5_vdpa_dev_add() and lets mlx5_vdpa_free() do its work. This issue was discovered while trying to add 2 vdpa devices with the same name: $> vdpa dev add name vdpa-0 mgmtdev auxiliary/mlx5_core.sf.2 $> vdpa dev add name vdpa-0 mgmtdev auxiliary/mlx5_core.sf.3 ... yields the following dump: BUG: kernel NULL pointer dereference, address: 00000000000000b8 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP CPU: 4 UID: 0 PID: 2811 Comm: vdpa Not tainted 6.12.0-rc6 #1 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 RIP: 0010:destroy_workqueue+0xe/0x2a0 Code: ...
