Remind me why did we remove them? What was the git hash?
15c6098cfec5 ("staging: android: ion: Remove ion_handle and ion_client")
According to Laura, "The goal was to rip out the racy handle/buffer mess
and the associated debugfs there"
Yes, the debugfs was removed with that commit because the underlying
handle/client were being removed and the associated debugfs
tended to race with tear down. There was also a question about what
information should go in Ion vs. dma_buf since Ion is now basically
a wrapper around dma_buf.
I don't disagree that we want some kind of debugfs counters but
I'd like to see some description of what problems we can solve
with this that aren't also solved by the debugfs with dma_buf.
Thanks,
Laura
