The one thing I learned about manpage CodingStyle is that new sentences
go on new lines.  I think this needs to be:

.TP
.BR MPOL_F_NUMA_BALANCING " (since Linux 5.11)"
Enable the Linux kernel NUMA balancing for the task if it is supported
by kernel.
If the flag isn't supported by Linux kernel, return -1 and errno is set
to EINVAL.
