Filipe Manana f89df93e8a btrfs: fix root leak if its reloc root is unexpected in merge_reloc_roots() ... [ Upstream commit ce6050bafb ] If we have an unexpected reloc_root for our root, we jump to the out label but never drop the reference we obtained for root, resulting in a leak. Add a missing btrfs_put_root() call. Fixes: 24213fa46c ("btrfs: do proper error handling in merge_reloc_roots") Reviewed-by: Qu Wenruo <wqu@suse.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		History 2026-08-19 17:13:52 +02:00
