As of xfsprogs commit 6e0ed3d1 ("mkfs: stop allowing tiny filesystems")
attempts to create XFS filesystems sized under 300M fail.
Lacking MIN_FSSIZE configuration, failure of _scratch_mkfs_sized() in
generic/027 doesn't halt the test, leading _scratch_mount() to mount any
previously created (full-size) filesystem. As a result create_file()
may loop near-endlessly awaiting ENOSPC.
Use a 300M sized filesystem to support XFS' limit, and explicitly check
for _scratch_mkfs_sized() failure to avoid endless loops if the limit
changes again in future.
