Marian Buschsieweke c790e2eb6d sys/malloc_thread_safety: use mutex ... Disabling IRQs during malloc() provides mutually exclusive access and even is safe from IRQ context, but is suboptimal for real time scenarios. Instead, the implementation is changed to use a mutex to provide mutually exclusive access. As a result, calls to malloc() and free() from IRQ context no longer is possible. But this this is a really horrible idea to begin with, the impact should be minimal and the improved real time properties of the system should make it a good trade-off. An assert() is added to allow easy detection of regressions and, hence, aid users to fix their code.		2020-12-17 15:39:05 +01:00
