From: Nadav Amit <namit@xxxxxxxxxx> There are inconsistencies and some issues in marking functions as notrace. On one hand, all inline functions are marked as "notrace" and some libraries cannot be traced. As more users and tools try to make use of the tracing functionality, it is beneficial to allow their tracing as possible. At the same time, some functions should not be traced but are not marked as notrace. These patch address issues that I encountered during work on an automatic tracing tool. --- v1->v2: * Add find_bit to tracable libraries * Improve the change log to explain the reasons for inline->notrace * Switch the order of patch 2 and patch 3 Nadav Amit (3): kprobes: Mark descendents of core_kernel_text as notrace compiler: inline does not imply notrace lib: Allow traceing of usercopy, xarray, iov_iter, find_bit arch/arm/kernel/process.c | 2 +- arch/ia64/mm/init.c | 2 +- arch/x86/entry/vsyscall/vsyscall_64.c | 2 +- arch/x86/um/mem_32.c | 2 +- include/asm-generic/sections.h | 6 +++--- include/linux/compiler_types.h | 2 +- include/linux/kallsyms.h | 6 +++--- include/linux/mm.h | 2 +- lib/Makefile | 5 +++++ 9 files changed, 17 insertions(+), 12 deletions(-) -- 2.25.1
