Hi!

This is a little fix to run quota_remount_test01.sh with SELinux enabled. 
Some distros (CentOS 6.x and, likely, RHEL 6) prevent from creation of quota 
files in 'file_t' directories, some - don't care. 
I tried this fix on CentOS 5.x/6.x and Oracle Linux, Debian 7. Seems, It's ok, and
should not break anything else.

And the test couldn't be invoked under 3.x kernels because of its kernel check. 
Changed it to use tst_kvercmp.

[LTP] [PATCH] quota_remount_test01: SELinux workaround and other fixes

[Stanislav Kholmanskikh]

From: Stanislav kholmanskikh <stanislav.kholmanskikh@oracle.com>

* now it uses tst_kvercmp (to support kernels >= 3)
* some distros doesn't allow creation of quota files in
directories with SELinux file_t type. Now we explicitly
change file type of the test directory to tmp_t

I can't check that the selinux specific bits works as they should, but
general idea of this patch is fine.

The supported_archs is supposed to work. How did you set it (the value)

Ah right, if addr is ignored just pass NULL there instead.

Hi Cyril.
Thanks for you quickly response.

Some of your point has been fixed. Some are not:
1. I'm using gcc (GCC) 11.4.1 20230605, `addr` without initialization would output some warnings.
2. I read the manpage of arch_prctl, the ARCH_GET_CPUID seems return the flag, instead of storing `addr`:
```
ARCH_GET_CPUID (since Linux 4.12)
              Return the setting of the flag manipulated by ARCH_SET_CPUID as the result of the system call (1  for  enabled,  0  for
              disabled).  addr is ignored.
```
I'm not sure if this is a problem of my environment.

Hi!

What kind of stress do you have in mind?

I guess that for CPU stress something as compiling kernel in a loop with
large enough -j parameter will suffice.

There are some test for OOM and memory overcommit, these are part of the
mm runtest file.

Unforunately that part of LTP is undercommented, you have to mostly
explore on your own, sorry.

Hi, all:

I want to ask if I can use ltp for stressing CPU and Memory with Linux OS?
If the answer is yes, Can I get the detailed explanation about the hierachy
of ltp because I think the document of ltp did not explain that.

Thanks very much !

It looks like the io_*.sh files are now not needed since the test source has been modified to check for an autoconf definition.
This patch modifies the syscalls runtest file to call those test directly. (io_cancel, io_destroy01, io_getevents01, 
io_setup01, io_submit01)

As the scripts are not needed any more, can we remove the following?

ltp/testcases/kernel/syscalls/io_cancel01.sh
ltp/testcases/kernel/syscalls/io_destroy01.sh
ltp/testcases/kernel/syscalls/io_getevents0101.sh
ltp/testcases/kernel/syscalls/io_setup01.sh
ltp/testcases/kernel/syscalls/io_submit01.sh

These scripts were not being copied into testcases/bin anyway and so AFAIK, did not run correctly by pan anyway.

Submitting a patch for the splice01 test. Previously the test was checking if the current working directory was NFS based as which the test. The patch changes this test to check whether the test directory is on NFS, as that is actually where the test gets run.
