2025-04-25test suite: use %zu to print size_tMatthew Wilcox (Oracle)
[ Upstream commit a30951d09c33c899f0e4aca80eb87fad5f10ecfa ] On 32-bit, we can't use %lu to print a size_t variable and gcc warns us about it. Shame it doesn't warn about it on 64-bit.

2025-01-23tools: fix atomic_set() definition to set the value correctlySuren Baghdasaryan
commit 4bbb6df62c54e6a2c1fcce4908df768f0cfa1e91 upstream. Currently vma test is failing because of the new vma_assert_attached() assertion. The check is failing because previous refcount_set() inside vma_mark_attached() is a NoOp. Fix the definition of atomic_set() to correctly set the value of the atomic.

2024-09-26tools: fix shared radix-tree buildLorenzo Stoakes
The shared radix-tree build is not correctly recompiling when lib/maple_tree.c and lib/test_maple_tree.c are modified - fix this by adding these core components to the SHARED_DEPS list. Additionally, add missing header guards to shared header files.

2024-09-01maple_tree: add test to replicate low memory race conditionsSidhartha Kumar
Add new callback fields to the userspace implementation of struct kmem_cache. This allows for executing callback functions in order to further test low memory scenarios where node allocation is retried. This callback can help test race conditions by calling a function when a low memory event is tested.

2024-09-01tools: separate out shared radix-tree componentsLorenzo Stoakes
The core components contained within the radix-tree tests which provide shims for kernel headers and access to the maple tree are useful for testing other things, so separate them out and make the radix tree tests dependent on the shared components. This lays the groundwork for us to add VMA tests of the newly introduced vma.c file.
