Subject: [PATCH 06/11] drivers/hyper_dmabuf: Remove from imported_list to
|
||
|
|
avoid exporting dma_buf later after receiving unexport notification
|
||
|
|
|
||
|
|
After the FE sends the UNEXPORT msg notification, it should not be
|
||
|
|
exported any more. So it needs to be removed from the imported_list.
|
||
|
|
In such case it can assure that it won't export the DMA_BUF again later
|
||
|
|
for imported ID info that is already released.

||
