The probe points are\n kept in an rbtree.\n\n If user-space executes the probed inode:offset instruction address\n then an event is generated which can be recovered from the regular\n perf event channels and mmap-ed ring-buffer.\n\n Multiple probes at the same address are supported, they create a\n dynamic callback list of event consumers.\n\n The basic model is further complicated by the XOL speedup: the\n original instruction that is probed is copied (in an architecture\n specific fashion) and executed out of line when the probe triggers.\n The XOL area is a single vma per process, with a fixed number of\n entries (which limits probe execution parallelism).\n\n The API: uprobes are installed/removed via\n /sys/kernel/debug/tracing/uprobe_events, the API is integrated to\n align with the kprobes interface as much as possible, but is separate\n to it.\n\n Injecting a probe point is privileged operation, which can be relaxed\n by setting perf_paranoid to -1.\n\n You can use multiple probes as well and mix them with kprobes and\n regular PMU events or tracepoints, when instrumenting a task.\"\n\nFix up trivial conflicts in mm/memory.c due to previous cleanup of\nunmap_single_vma().\n\n* \u0027perf-uprobes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits)\n perf probe: Detect probe target when m/x options are absent\n perf probe: Provide perf interface for uprobes\n tracing: Fix kconfig warning due to a typo\n tracing: Provide trace events interface for uprobes\n tracing: Extract out common code for kprobes/uprobes trace events\n tracing: Modify is_delete, is_return from int to bool\n uprobes/core: Decrement uprobe count before the pages are unmapped\n uprobes/core: Make background page replacement logic account for rss_stat counters\n uprobes/core: Optimize probe hits with the help of a counter\n uprobes/core: Allocate XOL slots for uprobes use\n uprobes/core: Handle breakpoint and singlestep exceptions\n uprobes/core: Rename bkpt to swbp\n uprobes/core: Make order of function parameters consistent across functions\n uprobes/core: Make macro names consistent\n uprobes: Update copyright notices\n uprobes/core: Move insn to arch specific structure\n uprobes/core: Remove uprobe_opcode_sz\n uprobes/core: Make instruction tables volatile\n uprobes: Move to kernel/events/\n uprobes/core: Clean up, refactor and improve the code\n ...\n" }, { "commit": "ab11ca34eea8fda7a1a9302d86f6ef6108ffd68f", "tree": "987ec6c263f3dfa4a7a6f9ce4d5ece47cbc12e29", "parents": [ "f9369910a6225b8d4892c3f20ae740a711cd5ace", "71006fb22b0f5a2045605b3887ee99a0e9adafe4" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 24 10:21:51 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 24 10:21:51 2012 -0700" }, "message": "Merge branch \u0027v4l_for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media\n\nPull media updates from Mauro Carvalho Chehab:\n -

Posted to LKML:\n https://lkml.org/lkml/2012/4/23/322.\n\n 3) A couple of commits that improve the efficiency of the interaction\n between preemptible RCU and the scheduler, these two being all that\n survived an abortive attempt to allow preemptible RCU\u0027s\n __rcu_read_lock() to be inlined. The full set was posted to LKML at\n https://lkml.org/lkml/2012/4/14/143, and the first and third patches\n of that set remain.\n\n 4) Lai Jiangshan\u0027s algorithmic implementation of SRCU, which includes\n call_srcu() and srcu_barrier(). A major feature of this new\n implementation is that synchronize_srcu() no longer disturbs the\n execution of other CPUs. This work is based on earlier\n implementations by Peter Zijlstra and Paul E. McKenney.

This commit therefore makes rcu_barrier() avoid\ninterrupting CPUs that have no callbacks. Doing this requires reworking\nthe handling of orphaned callbacks, otherwise callbacks could slip through\nrcu_barrier()\u0027s net by being orphaned from a CPU that rcu_barrier() had\nnot yet interrupted to a CPU that rcu_barrier() had already interrupted.\nThis reworking was needed anyway to take a first step towards weaning\nRCU from the CPU_DYING notifier\u0027s use of stop_cpu().\n\nSigned-off-by: Paul E.
