This series is a follow up of the clean up `-Wshorten-64-to-32` warnings that I discussed with Dylan previously. It only addresses the warnings in the src/ dir (main library). We ignore the tests for now. `-Wshorten-64-to-32` is a clang-specific flag, it currently doesn't exist in GCC. There are 3 patches in this series: - Patch 1 is to clean up the warnings in the main library (this is based on a patch from Dylan). Taken from: https://github.com/DylanZA/liburing/commit/cdd6dfbb9019.patch - Patch 2 is to introduce LIBURING_CFLAGS variable in the Makefile. We need this varaible to apply specific compiler flags to the main library only. Currently, this flag is only used by the GitHub bot. - Patch 3 is to integrate `-Wshorten-64-to-32` flag to the GitHub bot.
