+# FS QA Test No. 707
+#
+# Ensure that metadump copies large directory extents
+#
+# Metadump helpfully discards directory (and xattr) extents that are
+# longer than 1000 blocks.  This is a little silly since a hardlink farm
+# can easily create such a monster.
+#
+# Now that we've upped metadump's default too-long-extent discard
+# threshold to 2^21 blocks, make sure we never do that again.

+# bytes for a dir data block / 264 bytes per dirent == ~248 dirents per
+# block.  8187 hashes/dablk / 248 dirents/dirblock = ~33 dirblocks per
