Description David Smith 2015-02-25 15:52:59 UTC

In the following kernel commit, support for the timerfd() syscall was added (in kernel 2.6.22):

Then in the following kernel commit, support for timerfd() was removed and instead the timerfd_create(), timerfd_gettime(), timerfd_settime() syscalls were added (in kernel 2.6.25):

    timerfd: new timerfd API                                                    
====

systemtap has syscall/nd_syscall support for timerfd(), but not for timerfd_create(), timerfd_gettime(), or timerfd_settime()
