In the 'perf test "mmap interface"' we try creating events for several tracepoints, but when perf_evsel__new() fails we're not showing which one is failing, fix that to help diagnosing problems, such as the syscall tracepoints ones being found and fixes in this merge window. Now the failing tests shows: # perf test -v "mmap interface" 4: Read samples using the mmap interface : --- start --- test child forked, pid 14311 <SNIP> perf_evsel__new(sys_enter_getppid) test child finished with -1 ---- end ---- Read samples using the mmap interface: FAILED! # Now to check why the syscalls:sys_enter_getppid is failing... # ls -la /sys/kernel/debug/tracing/events/syscalls/sys_enter_getppid ls: cannot access '/sys/kernel/debug/tracing/events/syscalls/sys_enter_getppid': No such file or directory # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Dominik Brodowski <linux@dominikbrodowski.net> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-44xk0ycdzrfzx1o9rklf5itl@git.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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
