Test io_setup invoked via syscall(2): 1. io_setup fails and returns -EFAULT if ctxp is NULL. 2. io_setup fails and returns -EINVAL if ctxp is not initialized to 0. 3. io_setup fails and returns -EINVAL if nr_events is -1. 4. io_setup fails and returns -EAGAIN if nr_events exceeds the limit. 5. io_setup succeeds if both nr_events and ctxp are valid. Signed-off-by: Xie Ziyao <xieziyao@huawei.com> --- v1->v2: 1. Add .needs_kconfig in this test. 2. Print values not variable names in TST_EXP_PASS(). 3. Use TST_EXP_PASS_SILENT() instead of TST_EXP_PASS() in cleanup. runtest/syscalls | 1 + testcases/kernel/syscalls/io_setup/.gitignore | 1 + .../kernel/syscalls/io_setup/io_setup02.c | 64 +++++++++++++++++++ 3 files changed, 66 insertions(+) create mode 100644 testcases/kernel/syscalls/io_setup/io_setup02.c -- 2.17.1
