    Correct. What I meant is that it's not a bug in the 2.2.14aa7.gz patch. It
    may be as well a 2.2.14 official bug of course (but more likely to be
    another race in the lowlatency patch).

    BTW, I just found another lowlatency patch bug:

    + /*
    + * Tough one to time-limit ...
    + */
    entry = entry->next;
    - if (!CAN_UNUSE(INODE(tmp)))
    + if (!CAN_UNUSE(INODE(tmp))) {
    + if (current->need_resched) {
    + INODE(tmp)->i_count++;
    + spin_unlock(&inode_lock);
    + schedule();
    + spin_lock(&inode_lock);
    + INODE(tmp)->i_count--;
    + }
    + }

    i_count-- won't release the inode correctly (think if the inode got
    deleted under the schedule).

    Drop the above changes and try again.
