Subject: [PATCH 03/10] staging: gasket: page table: use GFP_KERNEL for dma_alloc_coherent
Date: Mon, 17 Sep 2018 05:38:58 -0700 [thread overview]
Message-ID: <20180917123905.213639-4-toddpoynor@gmail.com> (raw)
In-Reply-To: <20180917123905.213639-1-toddpoynor@gmail.com>
From: Todd Poynor <toddpoynor@google.com>
Flags should be specified for dma_alloc_coherent() call. Use
GFP_KERNEL, it's fine to sleep here.
