From d054422eb609da97699d900959bc9a351761f313 Mon Sep 17 00:00:00 2001 From: Kemeng Shi Date: Sat, 3 Jun 2023 23:03:18 +0800 Subject: [PATCH] ext4: fix wrong unit use in ext4_mb_clear_bb commit 247c3d214c23dfeeeb892e91a82ac1188bdaec9f upstream. Function ext4_issue_discard need count in cluster. Pass count_clusters instead of count to fix the mismatch.
