Subject: module: rename module_blacklist to module_denylist
Date: Tue, 8 Sep 2026 16:32:30 -0400

To preserve the existing user-space ABI, "module_blacklist=" is kept as a
legacy alias pointing to the same module_denylist variable.

This patch addresses the documentation by marking "module_blacklist=" as
deprecated in admin-guide/kernel-parameters.txt, and documents the new
"module_denylist=" parameter.  All internal symbols, such as
module_is_blacklisted(), have been renamed to use "denylist" and all log
messages now use "denylisted".
