    JFS: simplify types to get rid of sparse warning
    
    jfs_metapage.c was using uints and unsigned ints inconsistently when
    regular ints suffice.

    JFS: use DIV_ROUND_UP where appropriate
    
    This replaces some macros and code, which do the same thing as DIV_ROUND_UP
    defined in kernel.h, to use the DIV_ROUND_UP macro.

    JFS is missing a memory barrier
    
    JFS is missing a memory barrier needed to close the critical section before
    clearing the lock bit. Use lock bitops for this.
    
    unlock_page() has a second barrier after clearing the lock, which is
    required because it checks whether the waitqueue is active without locks.
    Such a barrier is not required here because the waitqueue spinlock is
    always taken (something to think about if performance is an issue).

    JFS: Make sure special inode data is written after journal is flushed
    
    This patch makes sure that data that we tried to flush before the journal
    was completely written actually gets pushed to disk.
    
    To avoid duplicating code, moved common code to write_special_inodes().

    JFS: clear PAGECACHE_TAG_DIRTY for no-write pages
    
    When JFS decides to drop a dirty metapage, it simply clears the META_dirty
    bit and leave alone the PG_dirty and PAGECACHE_TAG_DIRTY bits.
    
    When such no-write page goes to metapage_writepage(), the `relic'
    PAGECACHE_TAG_DIRTY tag should be cleared, to prevent pdflush from
    repeatedly trying to sync them.  This is done through
    set_page_writeback(), so call it should be called in all cases.  If
    no I/O is initiated, end_page_writeback() should be called immediately.
    
    This is how __block_write_full_page() does things.
