    SubjectRe: [PATCH] mm: D-cache aliasing issue in cow_user_page
    In light of James Bottomsley's commit[1] declaring that kmap() and
    friends now have to take care of coherency issues, is the patch "mm:
    D-cache aliasing issue in cow_user_page"[2] correct, or could it
    potentially cause a slowdown by calling flush_dcache_page() a second
    time (i.e. once in an architecture-specific kmap() implementation, and
    once in cow_user_page())?
