after read your patch, today (although I am not a reviewer).
is it a possible situation like this (just my imagination):
1st let it call clear_qf_name successfully.
2nd let it call set_qf_name successfully.
3rd call clear_qf_name again ?
...
if this situation is possible.
I guess the memory still leak, after apply your patch.
if what I guess is true
it seems we have to duplicate memory for old_opts in ext3_remount.
and for clear_qf_name, set_qf_name, ext3_remount:
use normal memory allocation and free ways instead of current using.
