[PATCH] ptrace, kernel 2.5.56

Hi,

According to Documentation/cachetlb.txt flush_dcache_page should also be 
called when the kernel _is about_ to read from a page and user space 
shared&writable mappings of this page potentially exist. I think 
kernel/ptrace.c should be fixed on this issue.
I already posted this patch on the lkml a few months ago, but it got lost 
I guess.
Where should I send ptrace patches to in the future? Anyone out there who 
maintains the ptrace stuff?

Frank.
