Subject: [PATCH 56/62] btrfs-progs: fix qgroup realloc inheritance

qgroup.c:83:23: warning: memcpy with byte count of 0

|
|
The inheritance wasn't copying qgroups[] because a confused sizeof()
|
||
|
|
gave 0 byte memcpy()s. It's been like this for the year since it was
|
||
|
|
merged, so I guess this isn't a very important thing to do :).
