    unix: don't use deprecated syscalls on linux/arm64 · fc8bd948
    Tobias Klauser authored
    On linux/arm64 we used to manually define syscall numbers for some
    deprecated syscalls. Most of them are unused by now anyhow. Convert the
    remaining syscall wrappers using them to implement the respective
    functionality using a non-deprecated syscall (in the same way glibc does
    it):
    
    - Implement EpollCreate using EpollCreate1 and additionally check
      that the passed size argument is larger than 0.
    - Implement Futimesat and utimes using utimensat. Also change futimesat
      on the other geese to take a string instead of *byte and let the
      generated wrapper do the BytePtrFromString conversion.
    - Return ENOSYS from Ustat. The ustat syscall has been deprecated for a
      long time in favor of fstatfs and statfs. Even glibc will deprecate
      ustat in the upcoming 2.28 release [1].
