Currently, the page allocated into fscache in readpage() 
for Cifs and Ceph does not be uncached if no data read due
to io error. This patch fixes this. fscache_readpages_cancel() 
is for this kind of job but taking list read * as input, so
a new routine taking page * as input is introduced. 

Li Wang (7):
  Fscache: Introduce new API fscache_readpage_cancel()
  Fscache: Implement uncaching single no-data page
  Ceph: Introduce routine for uncaching single no-data page
  Ceph: Uncaching no-data page in readpage()
  Cifs: Introduce routine for uncaching single no-data page
  Cifs: Implement uncaching single no-data page
  Cifs: Uncaching no-data page in readpage()
