New Revision: 367943
URL: https://svnweb.freebsd.org/changeset/base/367943
Log:
freebsd32: take the _umtx_op struct definitions back
Providing these in freebsd32.h facilitates local testing/measuring of the
structs rather than forcing one to locally recreate them. Sanity checking
offsets/sizes remains in kern_umtx.c where these are typically used.
