+Subject: [PATCH 1/2] tests/discard: Ensure a significant number of blocks are
+ freed up on the host.
+
+It's reasonable to expect megabytes will be freed up and given back to
+the host.  Previously we just tested that at least 1 block was
+released.  This test checks that at least 1000 blocks are released
+(since stat(2) returns blocks of 512 bytes: 512 bytes * 1000 = approx 0.5 MB).
