Introduce perf_cache object and interfaces to create, add entries, commit, and delete the object. perf_cache represents a file for the cached "perf probe" definitions on one binary file or vmlinux which has its own build id. The probe cache file is located under the build-id cache directory of the target binary, as below; <perf-debug-dir>/.build-id/<BU>/<ILDID>/probe Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> 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: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20160615032830.31330.84998.stgit@devbox Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
