[PATCH v3 25/34] s390/diag: Unpoison diag224() output buffer

2023-12-13 Thread Ilya Leoshkevich

Diagnose 224 stores 4k bytes, which cannot be deduced from the inline assembly constraints. This leads to KMSAN false positives. Unpoison the output buffer manually with kmsan_unpoison_memory(). Signed-off-by: Ilya Leoshkevich --- arch/s390/kernel/diag.c | 2 ++ 1 file changed, 2 insertions(+)
