Pull block fixes from Jens Axboe: "A set of fixes for block that should go into this tree. A bit larger than what I usually have at this point in time, a lot of that is the continued fixing of the lockdep annotation for queue freezing that we recently added, which has highlighted a number of little issues here and there. This contains: - MD pull request via Yu: - Add a legacy_async_del_gendisk mode, to prevent a user tools regression. New user tools releases will not use such a mode, the old release with a new kernel now will have warning about deprecated behavior, and we prepare to remove this legacy mode after about a year later - The rename in kernel causing user tools build failure, revert the rename in mdp_superblock_s - Fix a regression that interrupted resync can be shown as recover from mdstat or sysfs - Improve file size detection for loop, particularly for networked file systems, by using getattr to get the size rather than the cached inode size. - Hotplug CPU lock vs queue freeze fix - Lockdep fix while updating the number of hardware queues - Fix stacking for PI devices - Silence bio_check_eod() for the known case of device removal where the size is truncated to 0 sectors" * tag 'block-6.17-20250822' of git://git.kernel.dk/linux: block: avoid cpu_hotplug_lock depedency on freeze_lock block: decrement block_rq_qos static key in rq_qos_del() block: skip q->rq_qos check in rq_qos_done_bio() blk-mq: fix lockdep warning in __blk_mq_update_nr_hw_queues block: tone down bio_check_eod loop: use vfs_getattr_nosec for accurate file size loop: Consolidate size calculation logic into lo_calculate_size() block: remove newlines from the warnings in blk_validate_integrity_limits block: handle pi_tuple_size in queue_limits_stack_integrity selftests: ublk: Use ARRAY_SIZE() macro to improve code md: fix sync_action incorrect display during resync md: add helper rdev_needs_recovery() md: keep recovery_cp in mdp_superblock_s md: add legacy_async_del_gendisk mode

xfrm_policy.sh, nft_flowtable.sh, and vrf-xfrm-tests.sh use 'ip xfrm' with SHA-1, either 'auth sha1' or 'auth-trunc hmac(sha1)'. That requires CONFIG_CRYPTO_SHA1, which CONFIG_INET_ESP intentionally doesn't select (as per its help text). Previously, the config for these tests relied on CONFIG_CRYPTO_SHA1 being selected by the unrelated option CONFIG_IP_SCTP. Since CONFIG_IP_SCTP is being changed to no longer do that, instead add CONFIG_CRYPTO_SHA1 to the configs explicitly.

2025-08-19selftests: drv-net: ncdevmem: make configure_channels() support combined ↵Jakub Kicinski
channels ncdevmem tests that the kernel correctly rejects attempts to deactivate queues with MPs bound. Make the configure_channels() test support combined channels. Currently it tries to set the queue counts to rx N tx N-1, which only makes sense for devices which have IRQs per ring type. Most modern devices used combined IRQs/channels with both Rx and Tx queues. Since the math is total Rx == combined+Rx setting Rx when combined is non-zero will be increasing the total queue count, not decreasing as the test intends. Note that the test would previously also try to set the Tx ring count to Rx - 1, for some reason. Which would be 0 if the device has only 2 queues configured.

2025-08-19selftests/mm: add test for invalid multi VMA operationsLorenzo Stoakes
We can use UFFD to easily assert invalid multi VMA moves, so do so, asserting expected behaviour when VMAs invalid for a multi VMA operation are encountered. We assert both that such operations are not permitted, and that we do not even attempt to move the first VMA under these circumstances. We also assert that we can still move a single VMA regardless. We then assert that a partial failure can occur if the invalid VMA appears later in the range of multiple VMAs, both at the very next VMA, and also at the end of the range. As part of this change, we are using the is_range_valid() helper more aggressively. Therefore, fix a bug where stale buffered data would hang around on success, causing subsequent calls to is_range_valid() to potentially give invalid results. We simply have to fflush() the stream on success to resolve this issue.

2025-08-19tools/testing: add linux/args.h header and fix radix, VMA testsLorenzo Stoakes
Commit 857d18f23ab1 ("cleanup: Introduce ACQUIRE() and ACQUIRE_ERR() for conditional locks") accidentally broke the radix tree, VMA userland tests by including linux/args.h which is not present in the tools/include directory. This patch copies this over and adds an #ifdef block to avoid duplicate __CONCAT declaration in conflict with system headers when we ultimately include this.

Check that the return value of KVM_GET_VCPU_MMAP_SIZE is non-negative before comparing with sizeof(kvm_run). If KVM_GET_VCPU_MMAP_SIZE fails, it will return -1, and `-1 > sizeof(kvm_run)` is true, so the ASSERT passes. There are no other locations in tools/testing/selftests/kvm that make the same mistake.
