This patch adds case to test fsync and fdatasync with power-cuts. The rule to check is: 1) fsync should guarantee all the inode metadata after power-cut, 2) fdatasync should guarantee i_size and i_blocks at least after power-cut. Note that, in XFS, it allocates more blocks when doing writes, so it should close the file before fsync in order to get actual i_blocks after power-cut. Or, it needs to do truncate the file with a specific size to turn it off at the beginning.
