On an FC1 machine during initscripts these patches give: EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly. Freeing unused kernel memory: 336k freed Write protecting the kernel read-only data: 787k VFS: Busy inodes after unmount of nfsd. Self-destruct in 5 seconds. Have a nice day...

NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory NFSD: unable to find recovery directory /var/lib/nfs/v4recovery NFSD: starting 90-second grace period VFS: Busy inodes after unmount of nfsd. Self-destruct in 5 seconds. Have a nice day... The same happens with just #1 and #2 applied. The .config is at http://www.zip.com.au/~akpm/linux/patches/stuff/config-vmm. The kernel won't compile with just patch #1 applied. Patches shouldn't go into git in that manner.
