Message

Couple unrelated devmem TCP fixes bundled in a series for some
convenience.

- fix naming and provide page_pool_alloc_netmem for fragged
netmem.

- fix issues with dma-buf dma addresses being potentially
passed to dma_sync_for_* helpers.

---

v3:
- Add documentation patch for memory providers. (Jakub)
- Drop netmem_prefetch helper (Jakub)

v2:
- Fork off the syzbot fixes to net tree, resubmit the rest here.


Mina Almasry (4):
  net: page_pool: rename page_pool_alloc_netmem to *_netmems
  net: page_pool: create page_pool_alloc_netmem
  page_pool: disable sync for cpu for dmabuf memory provider
  net: Document netmem driver support

Samiullah Khawaja (1):
  page_pool: Set `dma_sync` to false for devmem memory provider
