NFS: remove 8 bytes of padding from struct nfs_fattr on 64 bit builds
remove 8 bytes of padding from struct nfs_fattr on 64 bit builds This also removes padding from several nfs structures, including 16 bytes from nfs4_opendata, nfs4_createdata,nfs3_createdata & 8 bytes from nfs_read_data,nfs_write_data,nfs_removeres,nfs4_closedata This also reduces the reported stack usage of many nfs functions (30+). Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk> ---- This patch is against the latest git 2.6.27-rc4. I've built & run this on my AMD64 desktop, & successfully run _simple_ tests with a 64 bit client => 32 bit server & 32 bit client to 64 bit server. On fedora with gcc (GCC) 4.3.0 20080428 (Red Hat 4.3.0-8) checkpatch reports 33 functions with reduced stack usage. e.g. __nfs_revalidate_inode [nfs] 216 => 200 _nfs4_proc_access [nfs] 304 => 288 _nfs4_proc_link [nfs] 536 => 504 _nfs4_proc_remove [nfs] 304 => 288 _nfs4_proc_rename [nfs] 584 => 552 nfs3_proc_access [nfs] 272 => 256 nfs3_proc_getacl [nfs] 384 => 368 nfs3_proc_link [nfs] 496 => 464 etc I can supply the complete list if anyone is interested. regards Richard Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
