From fec9b9d3ced39f16be8d7afdf81f4dd2653da319 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Miquel=20Sabat=C3=A9=20Sol=C3=A0?= Date: Wed, 8 Oct 2025 14:18:59 +0200 Subject: [PATCH] btrfs: fix memory leaks when rejecting a non SINGLE data profile without an RST MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit At the end of btrfs_load_block_group_zone_info() the first thing we do is to ensure that if the mapping type is not a SINGLE one and there is no RAID stripe tree, then we return early with an error. Doing that, though, prevents the code from running the last calls from this function which are about freeing memory allocated during its run. Hence, in this case, instead of returning early, we set the ret value and fall through the rest of the cleanup code.
