This can be seen by running `readelf -S file.o | grep GNU-stack | grep X`, for instance that happens in libdiskfs/file-exec.c, libdiskfs/io-revoke.c. We can't really use -fno-trampoline, we should instead add `void *data` parameters to iterators such as `ports_class_iterate` or `fshelp_exec_reauth`, so that the nested functions can be made mere static functions that get their information from the `void *data` parameter. * Implement `pthread_setschedparam` and `sched_setscheduler` in glibc by calling mach's `thread_policy` and `thread_priority`. * Strengthen httpfs: it should append '/' to URL automatically, it should not fallback index.html itself, etc. probably a lot more small easy issues. @@ -101,7 +100,6 @@ with".
