i brought up this issue on the KJ list once upon a time: https://lists.linux-foundation.org/pipermail/kernel-janitors/2007-February/017847.html and there didn't seem to be much enthusiasm for it. however, i am still curious why there isn't more use of the already-defined "clear_page" macro. most architectures appear to define it: $ grep -r "define.*clear_page" include but there are still numerous explicit calls to memset() to zero a chunk of memory that is exactly PAGE_SIZE in size. just an observation. rday -- ======================================================================== Robert P.
