Subject: [PATCH] Clean up group struct in _stats_create_group() error path
Conflict: NA
Reference: https://sourceware.org/git/?p=lvm2.git;a=commitdiff;h=eda99fc3839dcd439270ba5977ca6628bd9752cc
Fix a double free in the error path from _stats_create_group() by
clearing the group struct embedded in the dm_stats handle before
returning:
device-mapper: message ioctl on (253:0) failed: Invalid argument
Could not create regions from file /var/tmp/File With Spaces.
free(): double free detected in tcache 2
Aborted (core dumped)
