memory page question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I found this strange after scanning some memory pages in a kernel module.
Some pages are flaged by SetPageAnon and SetPageLRU and SetPageActive,
and yet it still has a page count of only one. I thought an anonymous page
should have at least a page count of one, and when it is on the LRU list, it should
have a page count of two. Is this right or a bug in the code? The version I'm looking
at is 2.6.6


Thanks

Hai
