Subject: [PATCH RFC 1/7] libfs: prepare to allow for non-immutable pidfd inodes
Date: Tue, 17 Jun 2025 17:45:11 +0200 [thread overview]
Message-ID: <20250617-work-pidfs-xattr-v1-1-d9466a20da2e@kernel.org> (raw)
In-Reply-To: <20250617-work-pidfs-xattr-v1-0-d9466a20da2e@kernel.org>
Allow for S_IMMUTABLE to be stripped so that we can support xattrs on
pidfds.
Signed-off-by: Christian Brauner <brauner@kernel.org>
