to clarify which system call accepts which arguments. Previously
the manual page gave the impression that calling unmount() with
flags of (MNT_FORCE | MNT_UPDATE | MNT_RDONLY) would downgrade a
read-write mount to read-only, which is clearly untrue; to do that,

Add a missing xref to sigsetops(3), without which the above three
syscalls would be useless.
TAI is a timescale, just like UTC. The tai field returns the offset
between the two, and isn't really used for precision time keeping.
Explain in brief what a positive and a negative leap seconds are. Add
some URLs to very useful web pages about time and time keeping for
more information on using this API.
