Those 2 tests fail on btrfs on a ppc64 system with 64k pages. This is
caused by the improved minimum device size calculation in upstream
btrfs-progs (commit: 31d228a2eb98 ("btrfs-progs: mkfs: Enhance minimal
device size calculation to fix mkfs failure on small file")).i
Xfstests implicitly uses '--mixed' options for filesystems smaller than
256mb thus the minimum filesystem size require is derived from the
following equation: 2 * (4mb + nodesize << 10). On a 64k page system
this evaluates to 2 * (4m + 64m) = 136m. This resuts in failures such:
mkfs.btrfs -b $((100 * 1048576)) btrfs-test.img
ERROR: size 104857600 is too small to make a usable filesystem
ERROR: minimum size for btrfs filesystem is 114294784
when running _scratch_mkfs_sized $((100 * 1048576)).
Fix this by increasing the minimum filesystem size to 196 megabytes
which makes mkfs.btrfs happy again and allows the test to proceed.
