In an AIM7 test, this commit degraded\nperformance by about 40%.\n\nThe commit runs rcu callbacks in a kthread instead of softirq. We observed\nhigh rate of context switch which is caused by this. Out test system has\n64 CPUs and HZ is 1000, so we saw more than 64k context switch per second\nwhich is caused by RCU\u0027s per-CPU kthread. A trace showed that most of\nthe time the RCU per-CPU kthread doesn\u0027t actually handle any callbacks,\nbut instead just does a very small amount of work handling grace periods.\nThis means that RCU\u0027s per-CPU kthreads are making the scheduler do quite\na bit of work in order to allow a very small amount of RCU-related\nprocessing to be done.\n\nAlex Shi\u0027s analysis determined that this slowdown is due to lock\ncontention within the scheduler. Unfortunately, as Peter Zijlstra points\nout, the scheduler\u0027s real-time semantics require global action, which\nmeans that this contention is inherent in real-time scheduling. (Yes,\nperhaps someone will come up with a workaround -- otherwise, -rt is not\ngoing to do well on large SMP systems -- but this patch will work around\nthis issue in the meantime. And \"the meantime\" might well be forever.)\n\nThis patch therefore re-introduces softirq processing to RCU, but only\nfor core RCU work. RCU callbacks are still executed in kthread context,\nso that only a small amount of RCU work runs in softirq context in the\ncommon case. This should minimize ksoftirqd execution, allowing us to\nskip boosting of ksoftirqd for CONFIG_RCU_BOOST\u003dy kernels.\n\nSigned-off-by: Shaohua Li \u003cshaohua.li@intel.com\u003e\nTested-by: \"Alex,Shi\" \u003calex.shi@intel.com\u003e\nSigned-off-by: Paul E.

__extent_writepage\n btrfs_writepage_end_io_hook\n\nPages are cirtical resourses and produce a lot of corner cases during writeback,\nso it is valuable to know how page is written to disk.\n\n4) inode:\n btrfs_inode_new\n btrfs_inode_request\n btrfs_inode_evict\n\nThese can show where and when a inode is created, when a inode is evicted.\n\n5) sync:\n btrfs_sync_file\n btrfs_sync_fs\n\nThese show sync arguments.\n\n6) transaction:\n btrfs_transaction_commit\n\nIn transaction based filesystem, it will be useful to know the generation and\nwho does commit.\n\n7) back reference and cow:\n\tbtrfs_delayed_tree_ref\n\tbtrfs_delayed_data_ref\n\tbtrfs_delayed_ref_head\n\tbtrfs_cow_block\n\nBtrfs natively supports back references, these tracepoints are helpful on\nunderstanding btrfs\u0027s COW mechanism.\n\n8) chunk:\n\tbtrfs_chunk_alloc\n\tbtrfs_chunk_free\n\nChunk is a link between physical offset and logical offset, and stands for space\ninfomation in btrfs, and these are helpful on tracing space things.\n\n9) reserved_extent:\n\tbtrfs_reserved_extent_alloc\n\tbtrfs_reserved_extent_free\n\nThese can show how btrfs uses its space.\n\nSigned-off-by: Liu Bo

On boot up, this array is read (much like\nthe initcall sections) and the events are processed.\n\nThe problem is that there is no guarantee that gcc will place complex\nstructures nicely together in an array format. Two structures in the\nsame file may be placed awkwardly, because gcc has no clue that they\nare suppose to be in an array.\n\nA hack was used previous to force the alignment to 4, to pack the\nstructures together. But this caused alignment issues with other\narchitectures (sparc).\n\nInstead of packing the structures into an array, the structures\u0027 addresses\nare now put into the _ftrace_event section. As pointers are always the\nnatural alignment, gcc should always pack them tightly together\n(otherwise initcall, extable, etc would also fail).\n\nBy having the pointers to the structures in the section, we can still\niterate the trace_events without causing unnecessary alignment problems\nwith other architectures, or depending on the current behaviour of\ngcc that will likely change in the future just to tick us kernel developers\noff a little more.\n\nThe _ftrace_event section is also moved into the .init.data section\nas it is now only needed at boot up.\n\nSuggested-by: David Miller \u003cdavem@davemloft.net\u003e\nCc: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nAcked-by: David S.
