Description
mdd_migrate() allocate 'la_size + 1' for symlink target name, the extra '+1' is a mistake, which will cause read beyond range fault: if target name is 59 bytes long, then it will try to read target name from external block other than inline i_block[15], that's why when target name is shorter than 59 it won't cause any problem.
