We were not considering 'B' and 'b' (BSS, uninitialized data objects, that gets set to zero at program start), do it so that we can resolve more symbols in tools doing resolution of data operands, like 'perf c2c'. When using vmlinux, i.e. an ELF symbol table, those were already considered, as the decision was about STT_FUNC or STT_OBJECT, and the later covers BSS symbols. # grep -i ' b ' /proc/kallsyms | head -20 | tail -5 ffffffffa789d030 b execute_command ffffffffa789d038 b initcall_command_line ffffffffa789d040 b static_command_line ffffffffa789d048 B ROOT_DEV ffffffffa789d050 b once.73786 # # readelf -s /lib/modules/`uname -r`/build/vmlinux | grep ROOT_DEV 79219: ffffffff8289d048 4 OBJECT GLOBAL DEFAULT 58 ROOT_DEV # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-z960xobig39ca1pmp5brl2fr@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.
