Subject[PATCH 8/8] perf tools: Make vmlinux short name more like kallsyms short name
Date
The previous patch changed kernel dso name from '[kernel.kallsyms]' to
vmlinux. However it might add confusion to old users accustomed to
the old name. So change the short name to '[kernel.vmlinux]' to
reduce such confusion.

Before:
# Overhead Command Shared Object Symbol

9.83% swapper vmlinux [k] intel_idle
4.10% awk libc-2.20.so [.] __strcmp_sse2
1.86% sed libc-2.20.so [.] __strcmp_sse2
1.78% netctl-auto libc-2.20.so [.] __strcmp_sse2
1.23% netctl-auto libc-2.20.so [.] __mbrtowc
1.21% firefox libxul.so [.] 0x00000000024b62bd
1.20% swapper vmlinux [k] cpuidle_enter_state
1.03% sleep vmlinux [k] copy_user_generic_unrolled
