Subject: The interface of flush_cache_page
Date: Sat, 4 Aug 2001 15:10:47 +0900 (JST) [thread overview]
Message-ID: <200108040610.f746AlJ19336@mule.m17n.org> (raw)
Currently, the interface is like this:
void flush_cache_page(struct vm_area_struct *vma, unsigned long address)
This doesn't work well for (virtuall indexed) physically tagged
architecture.
When it is called from vmscan.c:try_to_swap_out, as the PTE is cleared
to be zero, we have no way to know what phisical address to match.
How about adding argument: struct page *page? With that, we have
information of physical memory.
