Revision 2d6b74baa7147251c30a46c4996e8cc224aa2dc5 authored by Riccardo Mancini on 15 July 2021, 16:07:06 UTC, committed by Arnaldo Carvalho de Melo on 15 July 2021, 20:25:27 UTC
ASan reports a memory leak of nsinfo during the execution of
# perf test "31: Lookup mmap thread"
The leak is caused by a refcounted variable being replaced without
dropping the refcount.
This patch makes sure that the refcnt of nsinfo is decreased whenever a
refcounted variable is replaced with a new value.
