Subject: [PATCH 03/16] capability: rename cpu_vfs_cap_data to vfs_caps
Date: Wed, 29 Nov 2023 15:50:21 -0600 [thread overview]
Message-ID: <20231129-idmap-fscap-refactor-v1-3-da5a26058a5b@kernel.org> (raw)
In-Reply-To: <20231129-idmap-fscap-refactor-v1-0-da5a26058a5b@kernel.org>
vfs_caps is a more generic name which is better suited to the broader
use this struct will see in subsequent commits.
