Subject: [RHEL7 PATCH 16/31] elflink: tests: Run tests only for default huge
|
|
page size
|
|
|
|
The elflink tests (linkhuge, linkhuge-nofd, linkhuge-rw and
|
|
linkshare) are usually linked in a way that ensures that the
|
|
ELF segment boundaries are aligned to the kernel's default
|
|
huge page size. Hence, run these tests only for the kernel's
|
|
default huge page size as the program segments will not be
|
|
remapped otherwise.
