xtime variable in kernel 4.0

xtime variable in kernel 4.0

[Mohammad A Khasawneh]

Hi everyone,

I'm trying to develop a syscall in kernel v4.0 which copies the xtime
variable to user space. I can find the variable in 3.X but it seems to have
been changed in 4.0. Can anyone point me to its location?

Thanks,
Mohammad Khasawneh

git is your friend, it shouldn't be hard to find where it went to, just
look at all commits that changed between the version you find it, and
the new one, and run 'git log path/filename.c'

I am wondering why you need to return the wall clock time to user
space. This seems unnecessary to me unless you can find some
applications
that need the wall clock time in order to function correctly.
