+Subject: [PATCH] tests: Adjust sizes in generic FS resize test for VFAT resize
+
+Similar change to e75820f -- when shrinking, libparted can change
+FAT from FAT32 to FAT16 but it can't change from FAT16 to FAT32
+when growing so we can't shrink (V)FAT below FAT32 minimal size
+in our tests if we want to grow it back.
