    f2fs: support multiple devices · 3c62be17

    This patch implements multiple devices support for f2fs.
    Given multiple devices by mkfs.f2fs, f2fs shows them entirely as one big
    volume under one f2fs instance.
    
    Internal block management is very simple, but we will modify block allocation
    and background GC policy to boost IO speed by exploiting them accoording to
    each device speed.
