netfs: Prepare to split read_helper.c
Rename netfs_rreq_unlock() to netfs_rreq_unlock_folios() to make it sound
less like it's dropping a lock on an netfs_io_request struct.
Remove the 'static' marker on netfs_rreq_unlock_folios() and declaring it
in internal.h preparatory to splitting the file.
Changes
=======
ver #2)
- Slide this patch to after the one adding netfs_begin_read().
- As a consequence, don't need to unstatic so many functions.
