Ah, I did mentioned it when I added COLLAPSE_RANGE to the fsx and
fsstress, but I forgot to cc you Namjae, sorry about that.
But about the patch. It seems a little bit weird to change kernel
for this. The way I am doing it is by changing ltp/fsx.c and
ltp.fsstress.c to disable the particular mode:

Or we can add environment variables to disable a particular
operation on fsx, or fsstress. I am not really sure whether we need
to change kernel in order to avoid testing particular fallocate
mode.
Thanks!
