[LTP] [PATCH 3/8] syscalls/io_pgetevents: Add support for time64 tests

Viresh Kumar viresh.kumar@linaro.org
Tue May 5 11:12:03 CEST 2020


This adds support for time64 tests to the existing io_pgetevents()
syscall tests.

While at it, also pass mode to SAFE_OPEN() to avoid any errors when the
tests are run for multiple variants together.

Also get rid of an extra copy of local fd variable, which is incorrect.
