    Subject[PATCH 1/7] zsmalloc: s/firstpage/page in new copy map funcs
    Date
    From: Seth Jennings <sjenning@linux.vnet.ibm.com>

    firstpage already has precedent and meaning the first page
    of a zspage. In the case of the copy mapping functions,
    it is the first of a pair of pages needing to be mapped.

    This patch just renames the firstpage argument to "page" to
    avoid confusion.
