    Subject[PATCH] [9/40] i386: rename struct paravirt_patch to paravirt_patch_site for clarity
    Date

    From: Jeremy Fitzhardinge <jeremy@goop.org>
    Rename struct paravirt_patch to paravirt_patch_site, so that it
    clearly refers to a callsite, and not the patch which may be applied
    to that callsite.
