在将context加入列表之前,我们会将它reset,这样该context只有它的初始malloc块,没有其他块。要成为候选者,上下文必须与列表中的其他上下文具有相同minContextSize/initBlockSize;但是不用考虑它的maxBlockSize,因为这不会影响初始块的大小。当前有两个空闲链表,一个用于ALLOCSET_DEFAULT_SIZES,一个用于ALLOCSET_SMALL_...
但是在底层中使用的地址还是物理地址(物理块),因此需要将逻辑地址转化为物理块的编号,这在文件"src/backend/storage/freespace/freespace.c"中定义了转换函数fsm_logical_to_physical()。其首先找到该层中每个结点对应的物理块的数量,然后根据该物理块的数量。
