Toshiyuki Okajima 22ef37eed6 page-writeback: fix the calculation of the oldest_jif in wb_kupdate() 
wb_kupdate() function has a bug on linux-2.6.30-rc5.  This bug causes
generic_sync_sb_inodes() to start to write inodes back much earlier than
our expectations because it miscalculates oldest_jif in wb_kupdate().

This bug was introduced in 704503d836
('mm: fix proc_dointvec_userhz_jiffies "breakage"').
