    JFS: Fix i_blocks accounting when allocation fails
    
    A failure in dbAlloc caused a directory's i_blocks to be incorrectly
    incremented, causing jfs_fsck to find the inode to be corrupt.

    JFS: Don't set log_SYNCBARRIER when log->active == 0
    
    If a metadata page is kept active, it is possible that the sync barrier logic
    continues to trigger, even if all active transactions have been phyically
    written to the journal.  This can cause a hang, since the completion of the
    journal I/O is what unsets the sync barrier flag to allow new transactions
    to be created.

    JFS: fsync wrong behavior when I/O failure occurs
    
    This is half of a patch that Qu Fuping submitted in April.  The first part
    was applied to fs/mpage.c in 2.6.12-rc4.
    
    jfs_fsync should return error, but it doesn't wait for the metadata page to
    be uptodate, e.g.:
    jfs_fsync->jfs_commit_inode->txCommit->diWrite->read_metapage->
    __get_metapage->read_cache_page reads a page from disk. Because read is
    async, when read_cache_page: err = filler(data, page), filler will not
    return error, it just submits I/O request and returns. So, page is not
    uptodate.  Checking only if(IS_ERROR(mp->page)) is not enough, we should
    add "|| !PageUptodate(mp->page)"
