Title:
memfd from ubuntu_kernel_selftests failed to build on B-5.4 (unknown
type name ‘__u64’)
Status in ubuntu-kernel-tests:
New
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
BugLink: https://bugs.launchpad.net/bugs/1944613
There are build issues in selftests/memfd/fuse_test.c where __u64 is not
defined. This is issue is probably due to the fact that in 5.4 there is
a type include in one of the includes in the file, however this include
probably was not there for 4.15. Regardless we fix this by including the
type file directly.
[Fix]
* selftests/memfd: fix __u64 not defined build issue
Add #include <asm/types.h> to define the type
[Test Plan]
Recompile tests to make sure they build and tests pass.
[Where problems could occur]
Should be no problems since we are adding an include file that userspace
files always have access to.
--------------------------------------------------------------------------
Failed to build on B/linux-hwe-5.4 5.4.0-85.95~18.04.1. This was observed in
previous cycles.
I am working on a fix for it right now.
