[PATCH] xfs: do not pass unused params to xfs_flush_pages

[Denys Vlasenko]

Hi David,

xfs_flush_pages() does not use some of its parameters, namely:
first, last and fiops.

This patch removes these parameters from all callsites.

Code size difference on 32-bit x86:

   text    data     bss     dec     hex filename
 390739    2748    1708  395195   607bb linux-2.6-xfs1-TEST/fs/xfs/xfs.o
 390567    2748    1708  395023   6070f linux-2.6-xfs2-TEST/fs/xfs/xfs.o

Compile-tested only.
