From: Jinrong Liang <cloudliang@tencent.com>
The following warning appears when executing: make -C tools/testing/selftests/kvm
rseq_test.c: In function ‘main’: rseq_test.c:237:33: warning: implicit declaration of function ‘gettid’; did you mean ‘getgid’? [-Wimplicit-function-declaration] (void *)(unsigned long)gettid()); ^~~~~~ getgid /usr/bin/ld: /tmp/ccr5mMko.o: in function `main': ../kvm/tools/testing/selftests/kvm/rseq_test.c:237: undefined reference to `gettid' collect2: error: ld returned 1 exit status make: *** [../lib.mk:173: ../kvm/tools/testing/selftests/kvm/rseq_test] Error 1
Use the more compatible syscall(SYS_gettid) instead of gettid() to fix it. More subsequent reuse may cause it to be wrapped in a lib file.
