Subject: [PATCH v2 7/9] fs: Rename SB_I_EVM_UNSUPPORTED to SB_I_EVM_HMAC_UNSUPPORTED
Date: Mon,  5 Feb 2024 13:25:04 -0500	[thread overview]
Message-ID: <20240205182506.3569743-8-stefanb@linux.ibm.com> (raw)
In-Reply-To: <20240205182506.3569743-1-stefanb@linux.ibm.com>

Now that EVM supports RSA signatures for previously completely
unsupported filesystems rename the flag SB_I_EVM_UNSUPPORTED to
SB_I_EVM_HMAC_UNSUPPORTED to reflect that only HMAC is not supported.
