apio	045efc7046	kernel, luna: Port non-VFS changes over from pull request #22 ... OwnedPtr, SharedPtr: Add operator bool Option, Result: Make try_move_value() non-const since it modifies the Option kernel: Switch to a stack we control for the main task as soon as we leave early boot Heap: Fix GPF caused when making many small allocations Heap: Avoid accessing a block after it's potentially deleted luna: Skip UBSAN.cpp in CMakeLists as that's not implemented yet luna: Use spinlocks in the heap implementation kernel, luna: Move Spinlock.h to luna Option: Use __builtin_launder to ensure that the compiler doesn't label this as UB SharedPtr: Implement make_shared using adopt_shared SharedPtr: Delete ptr on failure in all adopt_shared* functions	2023-02-25 17:47:58 +01:00

apio	37bbc04719	Heap: Fix GPF caused when making many small allocations ... Apparently space was too tight to split(), but we did it anyways, corrupting the next block. This patch fixes this behavior.	2023-02-17 22:47:15 +01:00
