Try making this change: -loopfs-$(CONFIG_BLK_DEV_LOOP) := inode.o +loopfs-objs := inode.o > > ~Shea > > On Mon, Sep 15, 2014 at 03:55:32PM -0500, Seth Forshee wrote: > > On Mon, Sep 15, 2014 at 04:38:44PM -0400, Shea Levy wrote: > > > Hi, > > > > > > I wanted to test these patches (to support creating and filling a disk > > > image containing a btrfs filesystem and several subvolumes as an > > > unprivileged user), but the build fails due to what looks like a missing > > > loopfs.c in fs/loopfs (or alternatively an erroneous line in > > > fs/loopfs/Makefile).
