[PATCH 0/4] nfs: remove the fileid field from struct nfs_inode
From: Jeff Layton
Date: Tue May 12 2026 - 12:30:50 EST
v7.1-rc1 contains patches to make inode->i_ino to be a u64. With this
change, there is no need to keep a separate "fileid" field in struct
nfs_inode.
This patchset eliminiates that field, and the inode number hashing
machinery that is no longer needed. This shaves 8 bytes off of each
nfs_inode.
Trond/Anna: please consider this for v7.2.
