linux.git/arch/um/include/asm/current.h, branch for-next Linux kernel source tree um: move thread info into task 2024-11-12T13:50:31+00:00 Benjamin Berg benjamin.berg@intel.com 2024-11-11T10:29:10+00:00 2f681ba4b352cdd5658ed2a96062375a12839755 This selects the THREAD_INFO_IN_TASK option for UM and changes the way that the current task is discovered. This is trivial though, as UML already tracks the current task in cpu_tasks[] and this can be used to retrieve it. Also remove the signal handler code that copies the thread information into the IRQ stack. It is obsolete now, which also means that the mentioned race condition cannot happen anymore.
