Message-ID: <loom.20121030T002407-501@post.gmane.org> Date: Mon, 29 Oct 2012 23:28:10 +0000 (UTC) From: Dmitry Osipenko <digetx@...il.com> To: linux-kernel@...r.kernel.org Subject: Re: [PATCH V2] dma: tegra: avoid channel lock up after free Also code looks not thread-safe, is it ok? For example we can protect prepare functions with a spinlock and add tegra_dma_terminate_all_locked for calling on channel freeing under spinlock to avoid reschedule.
