From 561cafebb2cf97b0927b4fb0eba22de6200f682e Mon Sep 17 00:00:00 2001 From: Jinrong Liang Date: Tue, 2 Aug 2022 15:12:40 +0800 Subject: selftests: kvm: Fix a compile error in selftests/kvm/rseq_test.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
