[PATCH v1 0/6] Move dma_buf_mmap_internal() to dynamic locking specification

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Recently, dma-buf got a common locking convention for importers and
exporters. All the dma-buf functions were moved to the new locking
convention, apart from the dma_buf_mmap_internal() that was missed out
by accident. This series moves dma_buf_mmap_internal() to the dynamic
locking specification and updates drivers that support mmaping of
dma-bufs to use the debug-assert of the lock.

Thanks to Daniel Vetter for spotting the missed function!
