BTW it looks to me 0a65bc27bd64 is from v6.15-rc3 (e.g. 6.15 development cycle), but it was backported to 6.14 stable as 99a0ad16dfd11 to v6.14.4. Obviously fixing commit d9ec73301099 has also been backported (to v6.14.8). Kind regards, Petr -- Mailing list info: https://lists.linux.it/listinfo/ltp
