Subject: LU-18337 tests: Fix racer division by 0 error message
X-Git-Tag: 2.16.51~63

LU-18337 tests: Fix racer division by 0 error message

'file' under file_create.sh is set as /mnt/lustre/racer/M/N
Currently M/N is used directly as mathematical operation
to determine whether "--block" (default) is to be passed as
option to 'migrate'. This was causing the divide by zero error
when N is 0. This patch changes 'file' to use only the last
part (ie N) instead of M/N when doing the mod by 8 operation.
