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