Subject: nfs-utils: clean up NFSCTL_* macros for handling protocol bits
X-Git-Tag: nfs-utils-1-2-1-rc3~6
X-Git-Url: https://git.decadent.org.uk/gitweb/?p=nfs-utils.git;a=commitdiff_plain;h=0d53a1d0ff5635d3af2f0d10e1f00f5de1353490

nfs-utils: clean up NFSCTL_* macros for handling protocol bits

They are a little hard to follow currently. Clean them up and add new
macros that can set these bits in addition to the ones that unset them.

Also add a new macro that reports when any valid protocol bit is set.
