[PATCH 6/6] ext4: calculate rec_len of ".." with correct name length 2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The rec_len of directory ".." should be ext4_dir_rec_len(2, NULL) instead
of ext4_dir_rec_len(1, NULL). Although ext4_dir_rec_len return the same
number either with name_len 1 or name_len 2, it's better use the right
name_len to make code more intuitive.
