Test if qgroup can handle de-reference reallocation.
What is "de-reference reallocation"?
Sorry, I'm not good at English. I mean "extent de-reference during
reallocation".
Well that's still not clear. It's not so much an English problem but
rather what do you mean with that concept.
Is is reading an extent (as a result of read or pread syscall for
e.g.), freeing an extent, or what?
thanks
freeing an extent,to be exactly thanks
Although current
qgroup can handle it, we still need to prevent any regression which may
break current qgroup.

Missing a short description here of what the test does (what it tests).
OK, I'll add this description.

Again, what is a "de-refer extent"? I've never seen this expression
