[Question]Can someone explain the context_freelists?

["Wen Yi" <wen-yi@xxxxxx>]

In MemoryContext source code:

/* context_freelists[0] is for default params, [1] for small params */

static AllocSetFreeList context_freelists[2] =
{
    {
        0, NULL
    },
    {
        0, NULL
    }

};

I really don't know what this variable mean, can someone share me with your view?

Thanks in advance!

Yours,

Wen Yi
