Subject: dma_zalloc_coherent broken with 57bf5a8963f80fb3828c46c3e3a5b2dd790e09a7
Date: Tue, 27 Mar 2018 10:12:54 +0200 (CEST) [thread overview]
Message-ID: <alpine.LFD.2.21.1803270944490.1726@schleppi> (raw)
Hi,
commit 57bf5a8963f80fb3828c46c3e3a5b2dd790e09a7 broke usage of dma
allocations specifying __GFP_ZERO by silently removing that flag.
Why should "the memory returned [] always be zeroed."?
Regards,
Sebastian
