New Revision: 236796
URL: http://svn.freebsd.org/changeset/base/236796
Log:
MFC r236465:
Update the print mask for decoding b_flags. Add print masks for
b_vflags and b_xflags_t and print them as well.
MFC r236487:
Fix typo. Use commas to separate flag printouts, in style with
other parts of function.
