[Devel] [PATCH hci-8.1 v2 2/6] ms/vdso/timens: Move functions to new file

[Konstantin Khorenko]

> As a preparation of the untangling of time namespaces and the vDSO, move
> the glue functions between those subsystems into a new file.
> 
> While at it, switch the mutex lock and mmap_read_lock() in the vDSO
> namespace code to guard().
