From 2f7dd9b86fe4076059e6a4a2a2c5d565afd76b9e Mon Sep 17 00:00:00 2001 From: Yichong Chen Date: Tue, 21 Jul 2026 17:11:52 +0800 Subject: [PATCH] isofs: release zisofs block pointer buffer head zisofs_fill_pages() reads the compressed block pointer table. The error paths release the current buffer_head, the loop also releases the old buffer_head when it advances. However, the success path leaves the last buffer_head referenced. Release it before returning success.
