From: Darrick J. Wong <djwong@xxxxxxxxxx> Prior to lazysbcount, the xfs mount code blindly trusted the value of the fdblocks counter in the primary super, which means that the kernel doesn't detect the fuzzed fdblocks value at all. V4 is deprecated and pre-lazysbcount V4 hasn't been the default for ~14 years, so we'll just skip these two tests on those old filesystems. Signed-off-by: Darrick J.
