This repost only widened the target audience for broader review, no code change happened. Please speak up now (or be silent till the next merge window). That is, if there are no objections, we plan pushing the tree into -next and asking Linus in the next merge window for comments. The patches are posted as a reply to this email and can be also obtained as a whole tree from: https://git.kernel.org/cgit/linux/kernel/git/jirislaby/kgraft.git/log/?h=kgraft Jiri Kosina (6): kgr: initial code kgr: x86: refuse to build without fentry support kgr: add procfs interface for per-process 'kgr_in_progress' kgr: make a per-process 'in progress' flag a single bit kgr: expose global 'in_progress' state through procfs kgr: x86: optimize handling of CPU-bound tasks Jiri Slaby (14): ftrace: Add function to find fentry of function ftrace: Make ftrace_is_dead available globally kgr: add testing kgraft patch kgr: update Kconfig documentation kgr: add Documentation kgr: trigger the first check earlier kgr: sched.h, introduce kgr_task_safe helper kgr: mark task_safe in some kthreads kgr: kthreads support kgr: handle irqs kgr: add MAINTAINERS entry kgr: add support for missing functions kgr: exercise non-present function kgr: fix race of stub and patching Libor Pechacek (1): kgr: rephrase the "kGraft failed" message Documentation/kgraft.txt | 44 ++++ MAINTAINERS | 9 + arch/x86/Kconfig | 2 + arch/x86/include/asm/kgraft.h | 61 ++++++ arch/x86/include/asm/thread_info.h | 6 +- arch/x86/kernel/entry_64.S | 9 + drivers/base/devtmpfs.c | 1 + drivers/scsi/scsi_error.c | 2 + drivers/usb/core/hub.c | 4 +- fs/jbd2/journal.c | 2 + fs/notify/mark.c | 5 +- fs/proc/base.c | 11 + include/linux/freezer.h | 2 + include/linux/ftrace.h | 4 + include/linux/kgraft.h | 90 ++++++++ include/linux/sched.h | 9 + kernel/Kconfig.kgraft | 10 + kernel/Makefile | 1 + kernel/hung_task.c | 5 +- kernel/kgraft.c | 430 +++++++++++++++++++++++++++++++++++++ kernel/kthread.c | 3 + kernel/rcu/tree.c | 6 +- kernel/rcu/tree_plugin.h | 10 +- kernel/smpboot.c | 2 + kernel/trace/ftrace.c | 30 +++ kernel/trace/trace.h | 2 - kernel/workqueue.c | 3 + mm/huge_memory.c | 1 + net/bluetooth/rfcomm/core.c | 2 + samples/Kconfig | 8 + samples/Makefile | 3 +- samples/kgraft/Makefile | 1 + samples/kgraft/kgraft_patcher.c | 99 +++++++++ 33 files changed, 864 insertions(+), 13 deletions(-) create mode 100644 Documentation/kgraft.txt create mode 100644 arch/x86/include/asm/kgraft.h create mode 100644 include/linux/kgraft.h create mode 100644 kernel/Kconfig.kgraft create mode 100644 kernel/kgraft.c create mode 100644 samples/kgraft/Makefile create mode 100644 samples/kgraft/kgraft_patcher.c -- 2.0.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
