Results from Linaro’s 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. */
/*--------------------------------------------------------------*/
