Subject: [PATCH 0/5] ovl: convert copyup credential override to cred guard
Date: Fri, 14 Nov 2025 23:45:21 +0100 [thread overview]
Message-ID: <20251114-work-ovl-cred-guard-copyup-v1-0-ea3fb15cf427@kernel.org> (raw)
Hey,
This is on top of the other overlayfs cleanup guard work I already sent
out. This simplifies the copyup specific credential override.
The current code is centered around a helper struct ovl_cu_creds and is
a bit convoluted. We can simplify this by using a cred guard. This will
also allow us to remove the helper struct and associated functions.
