CLOCK_REALTIME in vdso data won't be updated if __arch_use_vsyscall() returns false.
Errm!
# git grep __arch_use_vsyscall #
Aside of that update_vsyscall() updates CLOCK_REALTIME data unconditionally. No idea what this patch is solving.
Cc: stable@vger.kernel.org # 5.4+
This # 5.4+ is pointless. You really want to add a fixes tag which pin points the commit which introduced the wreckage.
But thats moot as this is not fixing anything not even in 5.4.
I assume this was developed against some Frankenkernel which has a messy backport or a snapshot of some development version of that vdso stuff.
Not that I want to know, but please make sure that something you send my way makes sense on sane kernels.
Oh well.
Thanks,
