[PATCH] kvm/rseq_test.c:Correct gettid func name kselftest

[Akhil Raj]

I got the following error message when I ran

make kselftest summary=1 TARGETS=kvm

rseq_test.c: In function ‘main’:
rseq_test.c:230:33: warning: implicit declaration of function ‘gettid’;
 did you mean ‘getgid’? [-Wimplicit-function-declaration]
          (void *)(unsigned long)gettid());
                                 ^~~~~~
                                 getgid
/tmp/ccNexT4G.o: In function `main':
linux_mainline/tools/testing/selftests/kvm/rseq_test.c:230:
	undefined reference to `gettid'
collect2: error: ld returned 1 exit status
../lib.mk:136:
	recipe for target 'linux_mainline/tools/testing/selftests/kvm/rseq_test' failed

As per suggestion

I renamed gettid to getgid

after rerunning the kselftest command

the following selftests messages were returned

not ok 7 selftests: kvm: hyperv_clock # exit=254
not ok 11 selftests: kvm: kvm_clock_test # exit=254
not ok 51 selftests: kvm: access_tracking_perf_test # exit=254
not ok 53 selftests: kvm: dirty_log_test # exit=254
not ok 58 selftests: kvm: max_guest_memory_test # TIMEOUT 120 seconds
not ok 60 selftests: kvm: memslot_perf_test # exit=142
