On newer btrfs-progs, the leaf header lines looks like this: leaf 5423104 items 1 free space 2918 generation 7 owner CSUM_TREE leaf 5423104 flags 0x1(WRITTEN) backref revision 1 It's two lines, not the old one line output. The new behavior is introduced in btrfs-progs commit 9cc9c9ab3220 ("btrfs-progs: print the eb flags for nodes as well"), included by v5.10 release. So the test case doesn't handle older output format and failed to locate the target leaf. [FIX] Instead of relying on the leaf flags line, use the much older "leaf items" line as the filter target, so we can support much older distros.
