So here I am wondering what effect this bug has upon our users, so I
can decide which kernel versions should be fixed. Jason didn't tell me
so I went to read the description of clear_tfile_check_list(). After a
brief chuckle, I stopped.

I then found Yurij's original report, so I know what's going on. But I
still can't write your changelog because I don't know whether this is a
regression and if it is, which patch caused the regression.

Wanna help out here please?
