I propose we rename libkern's min/max to umin/umax. The names min and max invite general use like MIN and MAX, but these functions truncate their arguments to unsigned first. We also have imin/imax, lmin/lmax, and ulmin/ulmax.
This came to my attention while working on a drmkms update, where Linux's min/max are generic, and a quick grep found, for example: https://nxr.netbsd.org/xref/src/sys/uvm/uvm_pglist.c#151 Objections?
