- * When a program's coredump is generated as ELF format, a section is created
- * per a vma. In ELF, the number of sections is represented in unsigned short.
- * This means the number of sections should be smaller than 65535 at coredump.
- * Because the kernel adds some informative sections to a image of program at
- * generating coredump, we need some margin. The number of extra sections is
- * 1-3 now and depends on arch. We use "5" as safe margin, here.
- *
- * ELF extended numbering allows more than 65535 sections, so 16-bit bound is
- * not a hard limit any more. Although some userspace tools can be surprised by
- * that.
