      perf record: Do not save pathname in ./debug/.build-id directory for vmlinux · 00dc8657
      由 Namhyung Kim 提交于 
      When perf record finishes a session, it pre-processes samples in order
to write build-id info from DSOs that had samples.

During this process it'll call map__load() for the kernel map, and it
ends up calling dso__load_vmlinux_path() which replaces dso->long_name.

But this function checks kernel's build-id before searching vmlinux path
so it'll end up with a cryptic name, the pathname for the entry in the
~/.debug cache, which can be confusing to users.

This patch adds a flag to skip the build-id check during record, so
that it'll have the original vmlinux path for the kernel dso->long_name,
not the entry in the ~/.debug cache.

Before:
  # perf record -va sleep 3
  mmap size 528384B
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.196 MB perf.data (~8545 samples) ]
  Looking at the vmlinux_path (7 entries long)
  Using /home/namhyung/.debug/.build-id/f0/6e17aa50adf4d00b88925e03775de107611551 for symbols

After:
  # perf record -va sleep 3
  mmap size 528384B
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.193 MB perf.data (~8432 samples) ]
  Looking at the vmlinux_path (7 entries long)
  Using /lib/modules/3.16.4-1-ARCH/build/vmlinux for symbols

      perf symbols: Use consistent name for the DSO binary type member · 5f70619d
      由 Arnaldo Carvalho de Melo 提交于 
      It was called "data_type", but in this context "data" is way too vague,
it could mean the "data" ELF segment, or something else.

Since we have dso__read_binary_type_filename() and the values this field
receives are all DSO__BINARY_TYPE_<FOO> we may as well call it
"binary_type" for consistency sake.

It also seems more appropriate since it determines if we can do
operations like annotation and DWARF unwinding, that needs more than
just the symtab, requiring access to ELF text segments, CFI ELF
sections, etc.
