Re: [PATCH v2 06/20] vmcore, procfs: introduce a flag to distinguish objects copied in 2nd kernel
2013/3/2 HATAYAMA Daisuke d.hatay...@jp.fujitsu.com:
The part of dump target memory is copied into the 2nd kernel if it
doesn't satisfy mmap()'s page-size boundary requirement. To
distinguish such copied object from usual old memory, a flag
MEM_TYPE_CURRENT_KERNEL is introduced. If this flag is set, the object
is considered being copied into buffer on the 2nd kernel.

[PATCH v2 06/20] vmcore, procfs: introduce a flag to distinguish objects copied in 2nd kernel
The part of dump target memory is copied into the 2nd kernel if it
doesn't satisfy mmap()'s page-size boundary requirement. To
distinguish such copied object from usual old memory, a flag
MEM_TYPE_CURRENT_KERNEL is introduced. If this flag is set, the object
is considered being copied into buffer on the 2nd kernel.
