reorder nfs4_sequence_args to remove 8 bytes of padding on 64 bit builds.
The size of this structure drops to 24 bytes from 32 and reduces the text size of nfs.ko. On my x86_64 size reports
text data bss 2.6.32-rc5 200996 8512 432 209940 33414 nfs.ko +patch 200884 8512 432 209828 333a4 nfs.ko
Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk>
---- patch against 2.6.32-rc5 only lightly tested but it seems to work both with 64 bit client -> 32 bit server & 32 bit client -> 64 bit server.
regards
Richard
