[ Upstream commit16203e9cd0] Without this we were not getting the thousands separator for big numbers. Noticed while developing 'perf bench uprobe', but the use of %' predates that, for instance 'perf bench syscall' uses it. Before: # perf bench uprobe all # Running uprobe/baseline benchmark... # Executed 1000 usleep(1000) calls Total time: 1054082243ns 1054082.243000 nsecs/op # After: # perf bench uprobe all # Running uprobe/baseline benchmark... # Executed 1,000 usleep(1000) calls Total time: 1,053,715,144ns 1,053,715.144000 nsecs/op # Fixes:c2a0820305("perf bench: Add basic syscall benchmark") Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andre Fredette <anfredet@redhat.com> Cc: Clark Williams <williams@redhat.com> Cc: Dave Tucker <datucker@redhat.com> Cc: Davidlohr Bueso <dave@stgolabs.net> Cc: Derek Barbosa <debarbos@redhat.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Tiezhu Yang <yangtiezhu@loongson.cn> Link: https://lore.kernel.org/lkml/ZH3lcepZ4tBYr1jv@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
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.
