src/sys/modules/compat_110: Makefile
Added Files:
src/sys/compat/common: sys_descrip_100.c
Removed Files:
src/sys/compat/common: sys_decrip_110.c
Log Message:
Rename dup3110 to dup3100 to match historical practice for NetBSD-11,
because we already have kevent100. Fix compat_dup3 to belong in compat_100
not compat_110.
