From b9af27d020e4fbc20529cfde494b2bb77ec39a4c Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Tue, 11 Mar 2025 15:50:50 +0000 Subject: [PATCH] btrfs: tests: fix chunk map leak after failure to add it to the tree commit 009ca358486ded9b4822eddb924009b6848d7271 upstream. If we fail to add the chunk map to the fs mapping tree we exit test_rmap_block() without freeing the chunk map. Fix this by adding a call to btrfs_free_chunk_map() before exiting the test function if the call to btrfs_add_chunk_map() failed.
