Charles,

current yaffs_vfs_multi.c compiles with warnings in linux-3.0 due to
yaffs_sync_object() having mismatched arguments.

In linux-3.0, struct file_operations fsync function pointer takes only
two args (equivalent to the version used for version 2.6.35).  Here's a
crude patch to make it compile on linux-3.0, but I'm looking to see when
the fsync function pointer was changed to take four args and will refine
this patch then.  With this change YAFFS builds/runs fine on linux-3.0
kernel.
