Ran misc-tests/038 in /root/btrfs-progs:
======================================================================
make test-misc TEST=038\*
[TEST] misc-tests.sh
[TEST/misc] 038-backup-root-corruption
./test.sh: line 33: [: bytenr=65536,: integer expression expected
Backup slot 2 is not in use
test failed for case 038-backup-root-corruption
make: *** [Makefile:401: test-misc] Error 1
======================================================================
It's caused by the wrong line filtered by
$(dump_super | grep root | head -n1 | awk '{print $2}').
The $(dump-super | grep root) outputs
======================================================================
superblock: bytenr=65536, device=/root/btrfs-progs/tests/test.img
root 30605312
chunk_root_generation 5
root_level 0
chunk_root 22036480
chunk_root_level 0
log_root 0
log_root_transid 0
log_root_level 0
root_dir 6
backup_roots[4]:
======================================================================
Here
"superblock: bytenr=65536, device=/root/btrfs-progs/tests/test.img" is
selected but not the line "root 30605312".
Restricting the awk rule can fix it.
Fixes: 78a3831d46ec ("btrfs-progs: tests: Test backup root retention logic")
