netfs: Add write_begin helper
Add a helper to do the pre-reading work for the netfs write_begin address
space op.
Changes
v6:
- Fixed a missing rreq put in netfs_write_begin()[3].
- Use DEFINE_READAHEAD()[4].
v5:
- Made the wait for PG_fscache in netfs_write_begin() killable[2].
v4:
- Added flag to netfs_subreq_terminated() to indicate that the caller may
have been running async and stuff that might sleep needs punting to a
workqueue (can't use in_softirq()[1]).
