SubjectRe: lowlatency-2.2.14-B1 + 2.2.14aa7 fixes crash, but...

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--;
+ }
continue;
+ }

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

Drop the above changes and try again.
