btrfs-progs: force overwrite should wipe stale SB
(I am unable to reproduce the issue, tried to go back with progs versions but still the same. So as of now this code remains untested, suggest to wait till we have a reproducible test case). Here is a test case which says it all.. mkfs.xfs -f $DEV mkfs.btrfs -f $DEV mount $DEV $MNT mount: /dev/vdiskc: more filesystems detected. This should not happen, use -t <type> to explicitly specify the filesystem type or use wipefs(8) to clean up the device. mount: you must specify the filesystem type with this patch btrfs_prepare_device() also wipes old FS if any, btrfs_prepare_device() is called after we have verified that user has provided -f option.
