# JFS: remove racy, redundant call to block_flushpage
# 
# __invalidate_metapages references mp->page after after releasing the
# meta_lock spinlock, without increasing the use count.  This is racy and
# unnecessary since setting the META_discard flag is sufficient.
# block_flushpage() will be called when the metapage is released.
