smb: server: make use of smbdirect_connection_{alloc,free}_send_io()

Browse source

These are basically copies of smb_direct_{alloc,free}_sendmsg() just
a bit simpler and with the gfp_mask mask abstracted.

For now we still use KSMBD_DEFAULT_GFP, which includes
__GFP_RETRY_MAYFAIL.

The only difference is that we use ib_dma_unmap_page() for all sges,
this simplifies the logic and doesn't matter as
ib_dma_unmap_single() and ib_dma_unmap_page() both operate
on dma_addr_t and dma_unmap_single_attrs() is just an
alias for dma_unmap_page_attrs().
We already had such an inconsistency in the client
code where we use ib_dma_unmap_single(), while we mapped
using ib_dma_map_page().
