bcachefs: set fgf order hint before starting a buffered write
Set the preferred folio order in the fgp_flags by calling
fgf_set_order(). Page cache will try to allocate large folio of the
preferred order whenever possible instead of allocating multiple 0 order
folios.
This improves the buffered write performance up to 1.25x with default
mount options and up to 1.57x when mounted with no_data_io option with
the following fio workload:
fio --name=bcachefs --filename=/mnt/test --size=100G \
--ioengine=io_uring --iodepth=16 --rw=write --bs=128k
