This case is quit simple by using madvise(MADV_PAGEOUT), but for verifying
the memory size of being swappd, we need to setup the memcg and attach test

Hello!
This series contains torture-test updates for v6.18:
1. Fix jitter.sh spin time.
2. Add --do-normal parameter to torture.sh help text.
3. Announce kernel boot status at torture-test startup.
4. Suppress "Writer stall state" reports during boot.
5.
kunit_kcalloc() may fail. parse_filter_attr_test() uses the returned
pointer without checking it, and then writes to parsed_filters[j],
which can lead to a NULL pointer dereference under low-memory
conditions.
Use KUNIT_ASSERT_NOT_ERR_OR_NULL() to abort the test on allocation

Sometimes a given system takes surprisingly long to boot, for example,

Thank you for doing this. This is a great start for testing mshare.
I do have some comments below.

The file_stressor test creates directories in the root filesystem and
performs mount namespace operations that can fail on NFS root filesystems
due to network filesystem restrictions and permission limitations.
Add NFS root filesystem detection using statfs() to check for
