2025-05-21selftests: harness: Stop using setjmp()/longjmp()Thomas Weißschuh
Usage of longjmp() was added to ensure that teardown is always run in commit 63e6b2a42342 ("selftests/harness: Run TEARDOWN for ASSERT failures") However instead of calling longjmp() to the teardown handler it is easier to just call the teardown handler directly from __bail(). Any potential duplicate teardown invocations are harmless as the actual handler will only ever be executed once since commit fff37bd32c76 ("selftests/harness: Fix fixture teardown"). Additionally this removes a incompatibility with nolibc, which does not support setjmp()/longjmp().

2025-05-21tools/nolibc: Add m68k supportDaniel Palmer
Add nolibc support for m68k. Should be helpful for nommu where linking libc can bloat even hello world to the point where you get an OOM just trying to load it.

2025-05-21tools/nolibc: include nolibc.h early from all header filesThomas Weißschuh
Inclusion of any nolibc header file should also bring all other headers. On the other hand it should also be possible to include any nolibc header files in any order. Currently this is implemented by including the catch-all nolibc.h after the headers own definitions. This is problematic if one nolibc header depends on another one. The first header has to include the other one before defining any symbols. That in turn will include the rest of nolibc while the current header has not defined anything yet. If any other part of nolibc depends on definitions from the current header, errors are encountered. This is already the case today. Effectively nolibc can only be included in the order of nolibc.h. Restructure the way "nolibc.h" is included. Move it to the beginning of the header files and before the include guards. Now any header will behave exactly like "nolibc.h" while the include guards prevent any duplicate definitions.

2025-05-21tools/nolibc: add target to check header usabilityThomas Weißschuh
Each nolibc header should be valid for inclusion irrespective of any special ordering requirements. Add a new make target, based on the old kbuild "make header_check" target to validate this requirement. For now the check fails, but the following commits will fix the issues.

2025-05-21io_uring: fix overflow resched cqe reorderingPavel Begunkov
Leaving the CQ critical section in the middle of a overflow flushing can cause cqe reordering since the cache cq pointers are reset and any new cqe emitters that might get called in between are not going to be forced into io_cqe_cache_refill().

2025-05-21nvme: avoid creating multipath sysfs group under namespace path devicesNilay Shroff
Commit 4dbd2b2ebe4c ("nvme-multipath: Add visibility for round-robin io-policy") introduced the creation of the multipath sysfs group under the NVMe head gendisk device node. However, it also inadvertently added the same sysfs group under each namespace path device which head node refers to and that is incorrect. The multipath sysfs group should only be exposed through the namespace head gendisk node. This is sufficient, as the head device already provides symbolic links to the individual namespace paths it manages. This patch fixes the issue by preventing the creation of the multipath sysfs group under namespace path devices, ensuring it only appears under the head disk node.
