    quota: Fix WARN_ON in lookup_one_len · c56818d7
    Jan Kara authored
    We should hold i_mutex when looking up quota files for journaled quotas,
    otherwise a WARN_ON in lookup_one_len triggers. The fact that we didn't
    hold i_mutex previously probably could not lead to a real bug since the
    filesystem is just being mounted / remounted read-write and thus the
    root directory cannot change anyway but it's definitely cleaner with
    i_mutex.
