Description of problem: when I did ltp test, there were some cases blocked, at least I found sync() make the mistakes, and also it couldn't use 'Ctrl-C' or 'kill -9' to kill the process. Version-Release number of selected component (if applicable): [zliu@ZhoupingLiu mtest06]$ uname -ri 3.3.2-1.fc17.x86_64 x86_64 [zliu@ZhoupingLiu mtest06]$ rpm -q coreutils coreutils-8.15-6.fc17.x86_6 How reproducible: 100% Steps to Reproduce: [zliu@ZhoupingLiu ~]$ cat test.c #include <unistd.h> #include <stdio.h> int main() { printf("test sync()\n"); sync(); return 0; } [zliu@ZhoupingLiu zliu]# ./test test sync() ^C^C^ as the above, can't endup the process Or you can directly run sync command to reproduce the issue: [root@ZhoupingLiu zliu]# sync ^C^C^ Actual results: the sync hang up Expected results: sync work fine Additional info: couldn't find the issue in RHEL7 Alpha and RHEL6.
