When mapping two adjacent memory areas A and B, the current implementation
merges them into one segment, known as area C. However, if areas A and B
are mapped again, there will be separate entries for A, C, and B in the
memory maps, as C divides A and B. This means that if A and
From: Lipei Liang
If we map two continuous memory area A and B, current implementation
will merge these two segments into one, as area C. But, if area A and
B are mapped again, after sort, there while be A, C, B in mem maps,
as A and B divided by C, these segs couldn't be merged. In other words,
