| Subject: perf script python: Fix export-to-postgresql.py occasional failure |
| |
| From: Adrian Hunter <adrian.hunter@intel.com> |
| |
| commit 25e11700b54c7b6b5ebfc4361981dae12299557b upstream. |
| |
| Occasional export failures were found to be caused by truncating 64-bit |
| pointers to 32-bits. Fix by explicitly setting types for all ctype |
| arguments and results. |
