Issue #9068 has been reported by normalperson (Eric Wong).

----------------------------------------
Feature #9068: [PATCH (trivial)] thread.c: reduce rb_mutex_t size by 8 bytes on x86_64
https://bugs.ruby-lang.org/issues/9068

Author: normalperson (Eric Wong)
Status: Open
Priority: Low
Assignee: 
Category: core
Target version: current: 2.1.0


gcc can pack the structure better when both 32-bit fields
are next to each other.

(I realized I could have 10K-100K Mutexes potentially in one of my projects,
 but maybe I'll change the design :)
