hello, can u please clarify the following points with reasons it is said that the kernel can access any pagecache within the system without any permission. *but here the question arises that if the kernel is accessing any pagecache which is present in any user address space, does a new pagecache get created by the kernel or the same pagecache is used by it? * *also can the same scenario applies when another userprocess want to access the pagecache entry of another user process ??* please can u exl\plain it. thank you On 11/20/06, gaurav <gaurav1207@xxxxxxxxx> wrote:
