dm-flakey can be used to emulate IO write error, however, when we also need to prevent the IO error for a specific range of the block device (eg., the log region of a XFS), we need to specify multiple dm targets for the dm device. Option --table can not accommodate the multiple dm targets case, so let dmsetup get the possible-multiple-targets table from standard input.
