# FS QA Test No. 527
#
# Regression test for incorrect validation of ondisk dquot type flags when
# we're switching between group and project quotas while mounting a V4
# filesystem.  This test doesn't actually force the creation of a V4 fs because
# even V5 filesystems ought to be able to switch between the two without
# triggering corruption errors.
#
# The appropriate XFS patch is:
# xfs: fix incorrect root dquot corruption error when switching group/project
# quota types

# Import common functions.
