Here is the third part of the unification time printing in the kernel. This time for struct timespec64. The first patch brings a support into printf() implementation (test cases and documentation update included) followed by the treewide conversion of the current users.
The idea is to have one or a few biggest users included, the rest can be taken next release cycle on the subsystem basis, but I won't object if the respective maintainers already give their tags. Depending on the tags received it may go via dedicated subsystem or via PRINTK tree. Petr, what do you think?
Note, not everything was compile-tested. Kunit test has been passed, though.
Changelog v2: - dropped wrong patches (Hans, Takashi) - fixed most of the checkpatch warnings (fdo CI, media CI) - collected tags
