To: neilb, Jes.Sorensen; +Cc: linux-raid, gqjiang, Zhilong Liu
1. use 'Tab' as the code style.
2. arrange the testing steps and provide the 'main' entrance.
3. draft the log_save feature, it captures the /proc/mdstat,
md superblock info, bitmap info and the detail dmesg.
4. modified the mdadm() func, adding the operation that clear
the superblock when create or build one new array, and it
would exit testing when mdadm command returned non-0 value.
5. delete no_errors() func, it only used in tests/04update-uuid,
I recommend the new mdadm() using method.
6. delete fast_sync() func.
7. testdev(), add the object file checking, otherwise this command
would create one regular file, it's one trouble thing.
8. add dmesg checking in do_test() func, it's necessary to check
dmesg whether or not printed abnormal message.
9. add checking conditions in main(), such as $pwd/raid6check need
exists, here is a prompt to remind users to 'make everything'
before testing; the $targetdir should mount under ext[2-4] FS,
because the external bitmap only supports ext, the bmap() API
of bitmap.c doesn't exist in all filesystem, such as btrfs.
