Subject: [RFC 0/2] ima: evm: Add kernel cmdline options to disable IMA/EVM
Date: Tue, 17 Dec 2024 12:25:23 -0800	[thread overview]
Message-ID: <20241217202525.1802109-1-song@kernel.org> (raw)

While reading and testing LSM code, I found IMA/EVM consume per inode
storage even when they are not in use. Add options to diable them in
kernel command line. The logic and syntax is mostly borrowed from an
old serious [1].
