    SubjectRe: [RFC PATCH 0/2] Loop device psuedo filesystem
    Hi Seth,

    I applied your patches to 3.15-rc7, and had the same problem, the build
    fails with:

    > make[3]: *** No rule to make target `fs/loopfs/loopfs.c', needed by `fs/loopfs/loopfs.o'. Stop.

    I've attached the config I used, I generated it via make allnoconfig and
    then enabled MODULES, BLK, BLK_DEV, and BLK_DEV_LOOP=m in make nconfig.

    The build succeeds if I set BLK_DEV_LOOP=y, so I'll go ahead with my
    testing using that.
