Nice work, thanks! Looping ioctl_loop01.c and ioctl_ficlone02.c I reproduce the problem after 171 iterations: ioctl_loop01.c:75: TPASS: access /sys/block/loop0/loop0p1 succeeds tst_device.c:321: TWARN: Detached device /dev/loop0 has leftover partitions Kind regards, Petr -- Mailing list info: https://lists.linux.it/listinfo/ltp
