This test is motivated by this inconsistency found in ext4 during random
crash consistency tests:
*** fsck.ext4 output ***
fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
Pass 1: Checking inodes, blocks, and sizes
Inode 12, end of extent exceeds allowed value
(logical block 33, physical block 33817, len 7)
Clear? no
Inode 12, i_blocks is 240, should be 184. Fix? no
This test uses device mapper flakey target to demonstrate the bug
found using device mapper log-writes target.
