Hi all, Add new tests to exercise code that got refactored in 5.14. The nested shutdown test simulates the process of recovering after a VM host filesystem goes down and the guests have to recover. v2: fix some bugs pointed out by the maintainer, add cpu offlining stress test v3: run against the test fs, and limit the io thread count If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=new-tests-for-5.14 --- tests/generic/726 | 74 +++++++++++++++++++++++++++++++++++++++++++++++++ tests/generic/726.out | 2 + 2 files changed, 76 insertions(+) create mode 100755 tests/generic/726 create mode 100644 tests/generic/726.out
