>> The code path that we use to reserve memory is generic and used by various paths in the JVM, but we log messages about failures to reserve large pages on the 'gc, heap, coops' tag set. This is confusing, so I propose to log this on 'os, map' instead. We already use that tag set to log memory reservation, so I think that's a decent tag set to use.
