From ec65def1045e4c7817b7f741a86dadae82877a93 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 8 Mar 2019 14:47:35 +0100 Subject: perf data: Support having perf.data stored as a directory The caller needs to set 'struct perf_data::is_dir flag and the path will be treated as a directory. The 'struct perf_data::file' is initialized and open as 'path/header' file. Add a check to the direcory interface functions to check the is_dir flag.
