519440468b
This patch adds support to make libcutils create and use memfd where possible, instead of ashmem. The libcutils library is made dynamic, since apps are still sending over ashmem FDs to processes and we are working on moving those apps away from ashmem. The best we can do for that is make the library work, and force apps in the long run to move away from directly using ashmem. Due to further complications mentioned in the 'NOTE' section of the patch, memfd is kept disabled for now, so nothing changes yet. To enable it, set the sys.use_memfd property (check user_debug build). Bug: 113362644 Change-Id: I491cb7841b664db5b1c26b3e07a440a14810e182 Signed-off-by: Joel Fernandes <joelaf@google.com>
