Hi, This is v3 of the seqlock patch series:
[PATCH v1 00/25] seqlock: Extend seqcount API with associated locks https://lore.kernel.org/lkml/20200519214547.352050-1-a.darw...@linutronix.de [PATCH v2 00/18] https://lore.kernel.org/lkml/20200608005729.1874024-1-a.darw...@linutronix.de It's based over: git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git locking/core to get Peter's lockdep irqstate tracking series below, which untangles mainline seqlock.h<=>sched.h 'current->' task_struct circular dependency: https://lkml.kernel.org/r/linuxppc-dev/20200623083645.277342...@infradead.org Changelog-v3: - Re-add lockdep non-preemptibility checks on seqcount_t write paths. They were removed from v2 due to the circular dependencies mentioned. - Slight rebase over the new v5.8-rc1 KCSAN seqlock.h changes - Collect seqcount_t call-sites acked-by tags Thanks, 8<-------------- Ahmed S. Darwish (20): Documentation: locking: Describe seqlock design and usage seqlock: Properly format kernel-doc code samples seqlock: Add missing kernel-doc annotations lockdep: Add preemption enabled/disabled assertion APIs seqlock: lockdep assert non-preemptibility on seqcount_t write seqlock: Extend seqcount API with associated locks dma-buf: Remove custom seqcount lockdep class key dma-buf: Use sequence counter with associated wound/wait mutex sched: tasks: Use sequence counter with associated spinlock netfilter: conntrack: Use sequence counter with associated spinlock netfilter: nft_set_rbtree: Use sequence counter with associated rwlock xfrm: policy: Use sequence counters with associated lock timekeeping: Use sequence counter with associated raw spinlock vfs: Use sequence counter with associated spinlock raid5: Use sequence counter with associated spinlock iocost: Use sequence counter with associated spinlock NFSv4: Use sequence counter with associated spinlock userfaultfd: Use sequence counter with associated spinlock kvm/eventfd: Use sequence counter with associated spinlock hrtimer: Use sequence counter with associated raw spinlock Documentation/locking/index.rst | 1 + Documentation/locking/seqlock.rst | 242 +++++ MAINTAINERS | 2 +- block/blk-iocost.c | 5 +- drivers/dma-buf/dma-resv.c | 15 +- .../gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c | 2 - drivers/md/raid5.c | 2 +- drivers/md/raid5.h | 2 +- fs/dcache.c | 2 +- fs/fs_struct.c | 4 +- fs/nfs/nfs4_fs.h | 2 +- fs/nfs/nfs4state.c | 2 +- fs/userfaultfd.c | 4 +- include/linux/dcache.h | 2 +- include/linux/dma-resv.h | 4 +- include/linux/fs_struct.h | 2 +- include/linux/hrtimer.h | 2 +- include/linux/kvm_irqfd.h | 2 +- include/linux/lockdep.h | 18 + include/linux/sched.h | 2 +- include/linux/seqlock.h | 872 ++++++++++++++---- include/linux/seqlock_types_internal.h | 186 ++++ include/net/netfilter/nf_conntrack.h | 2 +- init/init_task.c | 3 +- kernel/fork.c | 2 +- kernel/time/hrtimer.c | 13 +- kernel/time/timekeeping.c | 19 +- lib/Kconfig.debug | 1 + net/netfilter/nf_conntrack_core.c | 5 +- net/netfilter/nft_set_rbtree.c | 4 +- net/xfrm/xfrm_policy.c | 10 +- virt/kvm/eventfd.c | 2 +- 32 files changed, 1211 insertions(+), 225 deletions(-) create mode 100644 Documentation/locking/seqlock.rst create mode 100644 include/linux/seqlock_types_internal.h base-commit: 997e89fa345e9006f311cf9f9c8fd9f7d96c240f -- 2.20.1 _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
