Hi ! I was looking at virtual address space of a process inside kernel space. I could see heap section and mmap section. Fragmentation and defragmentation problem against the memory allocated from heap section is handled by language runtime (glibc) and that's where most of memory management algorithms do work.
I can see following declarations in struct mm_struct: unsigned long start_brk, brk, unsigned long mmap_base; According to these declarations heap segment has start and end pointers but for mmap segment only base pointer is present but no end. Then how one would know the total memory consumed by mmap segment. Also how fragmentation problem in mmap segment is handled??
