Subject: [PATCH 4/4] nfs: remove fileid field from struct nfs_inode
Date: Tue, 12 May 2026 12:12:45 -0400	[thread overview]
Message-ID: <20260512-nfsino-v1-4-284720522f4c@kernel.org> (raw)
In-Reply-To: <20260512-nfsino-v1-0-284720522f4c@kernel.org>

Now that all NFS client code uses inode->i_ino directly to store and
access the 64-bit NFS fileid, the separate fileid field in struct
nfs_inode is unused. Remove it to save 8 bytes per NFS inode.
