Subject: [PATCH v2 0/3] udmabuf: Sync to attached devices

Hello all,

This series makes it so the udmabuf will sync the backing buffer
with the set of attached devices as required for DMA-BUFs when
doing {begin,end}_cpu_access.

Thanks
Andrew

Changes for v2:
 - fix attachment table use-after-free
 - rebased on v6.17-rc1

Andrew Davis (3):
  udmabuf: Keep track current device mappings
  udmabuf: Sync buffer mappings for attached devices
  udmabuf: Use module_misc_device() to register this device
