The first fix takes care of an issue that arose in the integration of the rseq patchset (executable bit on run_param_test.sh was lost). The second fix aligns struct rseq_cs on 32 bytes on arm32, following the rseq.h alignment requirements. The last patch is a cleanup: given that we have decided that system calls were not allowed in rseq critical sections, fork/clone cannot be done in a rseq c.s.. Therefore, there is no need to abort a rseq critical section within the child on fork of a new process. Thanks, Mathieu Mathieu Desnoyers (3): rseq/selftests: run_param_test.sh should be executable rseq/selftests: arm: align struct rseq_cs on 32 bytes rseq: cleanup: no need to abort rseq c.s. in child on fork include/linux/sched.h | 5 +---- tools/testing/selftests/rseq/rseq-arm.h | 1 + tools/testing/selftests/rseq/run_param_test.sh | 0 3 files changed, 2 insertions(+), 4 deletions(-) mode change 100644 => 100755 tools/testing/selftests/rseq/run_param_test.sh -- 2.11.0
