Subject: [PATCH] fuse: Return EPERM rather than ENOSYS from link()
Date: Fri, 14 Feb 2025 09:17:53 +0800	[thread overview]
Message-ID: <20250214-fuse-link-eperm-v1-1-8c241d987008@codeconstruct.com.au> (raw)

link() is documented to return EPERM when a filesystem doesn't support
the operation, return that instead.
