e2a157f380 btrfs-progs: fix compiler warning
gcc 4.9.0 gives a warning: format ‘%d’ expects argument of type ‘int’,
but argument 2 has type ‘u64’

Using %llu and casting to unsigned long long (same as bytenr) fixes this.

555ae67390 btrfs-progs: btrfs-select-super output is confusing when it fails
Trivial patch:
./btrfs-progs/btrfs-select-super -s 0 /dev/sdc
using SB copy 0, bytenr 65536
No valid Btrfs found on /dev/sdc
Open ctree failed

The line 'using..' is confusing which gives an
indication that command is successful

This patch will avoid that when command fails

b4382217f1 Btrfs-progs: add a btrfs-select-super command to overwrite the super
Btrfs stores multiple copies of the superblock, and for common power-failure
crashes where barriers were not in use, one of the super copies is often
valid while the first copy is not.

This adds a btrfs-select-super -s N /dev/xxx command, which can
overwrite all the super blocks with a copy that you have already
determined is valid with btrfsck -s
