Subject: [RESEND PATCH 0/7] Cifs and Ceph: Uncache single no-data page in readpage()

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()
