Sigh. In theory drivers should never declare coherent memory like
this, and there has been some work to fix remoteproc in that regard.
But I guess until that is merged we'll need somthing like this fix.
Hi,
Thanks for your comment.
As I didn't see other fix of this issue, should we use this patch
before the remoteproc work you mentioned is merged?
TBH I think it would be better "fixed" with a kmemleak_ignore() and a
big comment, rather than adding API cruft for something that isn't a
real problem. I'm quite sure that no real-world user is unbinding
remoteproc drivers frequently enough that leaking a 48-byte allocation
each time has any practical significance.
Thanks,
Robin.
