Results from Linaro=E2=80=99s test farm.
Regressions detected.

LTP syscalls failed test cases on all devices arm64, arm32 and x86_64,
 - creat08
 - open10

Reported this bug internally on upstream Linux mainline week back.
Now this bug happening on 4.17, 4.14, 4.9 and 4.4

creat08 and open10 failed with this error,
TFAIL  : testdir.B.3132/setgid: Incorrect modes, setgid bit should be set

Test case description:
/*
 * NAME
 * creat08.c - Verifies that the group ID and setgid bit are
 *    set correctly when a new file is created.
 *    (ported from SPIE, section2/iosuite/creat5.c,
 *     by Airong Zhang <zhanga@us.ibm.com>)
 * CALLS
 * creat
 *
 * ALGORITHM
 * Create two directories, one with the group ID of this process
 * and the setgid bit not set, and the other with a group ID
 * other than that of this process and with the setgid bit set.
 * In each directory, create a file with and without the setgid
 * bit set in the creation modes. Verify that the modes and group
 * ID are correct on each of the 4 files.
 * As root, create a file with the setgid bit on in the
 * directory with the setgid bit.
 * This tests the SVID3 create group semantics.
 */

Block2 testing:
/*--------------------------------------------------------------*/
/* Block2: Create two files in testdir.B, one with the setgid   */
/*         bit set in the creation modes and the other without. */
/*    Both should inherit the group ID of the parent       */
/*    directory, group2.                                   */
