RH-Commit: [15/50] 89db3c8b167c0f411ba95ce2730540c0e8f1206b (peterx/qemu-kvm)
|
|
|
|
Rest of counters that refer to pages has a _pages suffix.
|
|
And historically, this showed the number of pages composed of the same
|
|
character, here comes the name "duplicated". But since years ago, it
|
|
refers to the number of zero_pages.
