RFR: 8229872: (fs) Increase buffer size used with getmntent

[Vladimir Kempik]

Hello

I’m planning to sync setmntent/getmntent on some object via MonitorEnter/Exit to prevent race condition.
But where to get some jobject ?
Should I pass it from caller (java method), but then It needs to be some static object.
Or should I create my own on first usage of setmntent ?

Thanks, Vladimir.
