perf buildid-cache: Use path/to/bin/buildid/elf instead of path/to/bin/buildid
Use path/to/bin/buildid/elf instead of path/to/bin/buildid to store corresponding elf binary. This also stores vdso in buildid/vdso, kallsyms in buildid/kallsyms. Note that the existing caches are not updated until user adds or updates the cache. Anyway, if there is the old style build-id cache it falls back to use it. (IOW, it is backward compatible) Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Ananth N Mavinakayanahalli <ananth@linux.vnet.ibm.com> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Hemant Kumar <hemant@linux.vnet.ibm.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20160528151537.16098.85815.stgit@devbox Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
