Hi all,
This patch set introduces a buffer synchronization framework based
on DMA BUF[1] and based on ww-mutexes[2] for lock mechanism, and
has been rebased on linux-next.
The purpose of this framework is to provide not only buffer access
control to CPU and CPU, and CPU and DMA, and DMA and DMA
This patch adds lock and poll callbacks to dma buf file operations,
and these callbacks will be called by fcntl and select system calls.
fcntl and select system calls can be used to wait for the completion
of DMA or CPU access to a shared dmabuf. The difference of them is

Smatch complains about the locking here because we mix spin_lock_irq()
with spin_lock_irqsave() in an unusual way. According to Smatch, it's
not always clear if the IRQs are enabled or disabled when we return. It
turns out this function is always called with IRQs enabled and we can
just use
