Subject: x86: vmalloc and THP
Date: Tue, 12 Aug 2014 08:01:41 +0300	[thread overview]
Message-ID: <53E99FB5.1020506@scalemp.com> (raw)

Hello,

Does memory allocated using vmalloc() will be mapped using huge pages 
either directly or later by THP ?

If not, is there any fast way to change this behavior ? Maybe by 
changing the granularity/alignment of such allocations to allow such 
mapping ?

Thanks,
Oren Twaig.
