Subject: [PATCH v4 1/8] landlock: Rename quiet_masks to quiet_access
Date: Fri, 2 Oct 2026 14:43:54 +0200 [thread overview]
Message-ID: <20261002124409.1277970-2-mic@digikod.net> (raw)
In-Reply-To: <20261002124409.1277970-1-mic@digikod.net>
The base stores the fs/net/scope quiet bitmasks in a struct access_masks
field named quiet_masks. A following commit adds the sibling struct
permission_masks field quiet_permission for capabilities and namespaces.
quiet_masks drops the access category and keeps the type half ("masks"),
while quiet_permission keeps the category and drops the type half, so
the two read as an inconsistent pair.
Rename the base field to quiet_access, giving the symmetric,
category-named pair quiet_access/quiet_permission that also matches the
UAPI handled_access_*/quiet_access_* naming. This is a
no-functional-change rename.
