sysret_check

[satishvb]

I am new to Linux and have a performance related question. When I profile hotspots in my application I see sysret_check comes up as top in the list. What is this function doing ?

this is my linux distribution
3.10.0-1160.45.1.el7.x86_64 #1 SMP Wed Oct 13 17:20:51 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

That's really your kernel version. This is a fairly old kernel.

Try cat /etc/os-release to see the distro version.
