Christoph Hellwig a8efc69a65 shmem: provide a shmem_write_folio wrapper 
Patch series "better block swap batching and a different take on swap_ops
v5".

This series makes use of the swap_iocb for block as well so that it
doesn't do inefficient single-bio I/O, and then rebases the swap_ops from
Baoquan on top of the now very different method structure.

When running doing kernels builds, which is a workload that doesn't really
do much THP anonymous memory it still gets 2x clustering for writeout and
1.2x for reading back swap in.  The overall times do not actually change,
though.


This patch (of 7):

Provide a wrapper for the shmem abuses in drm to prepare for swap I/O
refactoring by keeping swap_iocb handling entirely contained in mm/.
