| H A D | dsos.c | 68566a7c Mon Jul 11 04:31:44 CDT 2022 Adrian Hunter <adrian.hunter@intel.com> perf tools: Fix dso_id inode generation comparison
Synthesized MMAP events have zero ino_generation, so do not compare
them to DSOs with a real ino_generation otherwise we end up with a DSO
without a build id.
Fixes: 0e3149f86b99ddab ("perf dso: Move dso_id from 'struct map' to 'struct dso'")
