Subject: [PATCH v2] erofs: Use %pe format specifier for error pointers
Date: Mon, 8 Dec 2025 17:31:38 +0800 [thread overview]
Message-ID: <20251208093138.127880-1-mengferry@linux.alibaba.com> (raw)
%pe will print a symbolic error name (e.g,. -ENOMEM), opposed to the
raw errno (e.g,. -12) produced by PTR_ERR().
