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()
