The check_variable() is used in other places which don't want to print the message. $ perf --debug type-profile annotate --data-type Before: ----------------------------------------------------------- find data type for 0x140(reg14) at update_blocked_averages+0x2db CU for kernel/sched/fair.c (die:0x12dd892) frame base: cfa=1 fbreg=7 no pointer or no type <<<--- removed check variable "__mptr" failed (die: 0x13022f1) variable location: base=reg14, offset=0x140 type='void*' size=0x8 (die:0x12dd8f9) After: ----------------------------------------------------------- find data type for 0x140(reg14) at update_blocked_averages+0x2db CU for kernel/sched/fair.c (die:0x12dd892) frame base: cfa=1 fbreg=7 found "__mptr" (die: 0x13022f1) in scope=4/4 (die: 0x13022e8) failed: no/void pointer <<<--- here variable location: base=reg14, offset=0x140 type='void*' size=0x8 (die:0x12dd8f9) Signed-off-by: Namhyung Kim <namhyung@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20240816235840.2754937-5-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
