      perf tools: Use __maybe_used for unused variables · 1d037ca1
      Irina Tirdea authored
      
      perf defines both __used and __unused variables to use for marking
      unused variables. The variable __used is defined to
      __attribute__((__unused__)), which contradicts the kernel definition to
      __attribute__((__used__)) for new gcc versions. On Android, __used is
      also defined in system headers and this leads to warnings like: warning:
      '__used__' attribute ignored
      
      __unused is not defined in the kernel and is not a standard definition.
      If __unused is included everywhere instead of __used, this leads to
      conflicts with glibc headers, since glibc has a variables with this name
      in its headers.
      
      The best approach is to use __maybe_unused, the definition used in the
      kernel for __attribute__((unused)). In this way there is only one
      definition in perf sources (instead of 2 definitions that point to the
      same thing: __used and __unused) and it works on both Linux and Android.
      This patch simply replaces all instances of __used and __unused with
      __maybe_unused.
