[LTP] [PATCH 1/2] syscalls/ioctl: ioctl_sg01.c: ioctl_sg01 invoked oom-killer

[liuxp11@chinatelecom.cn]

safety = MAX(4096 * SAFE_SYSCONF(_SC_PAGESIZE), 128 * 1024 * 1024);
now safety margin is 128MB,not 64MB. Right?

Yep, there it is. min_free_kbytes is 90MB but we only leave 64MB safety
margin. I'll prepare a patch that'll increase safety margin to
2*min_free_kbytes if needed.
