Subject: avoid OPEN_MAX in SCM_MAX_FD
X-Git-Tag: firefly_0821_release~27912
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c09edd6eba683741bb8aa8e388a2bfaf1c1a28f9;p=firefly-linux-kernel-4.4.55.git

avoid OPEN_MAX in SCM_MAX_FD

The OPEN_MAX constant is an arbitrary number with no useful relation to
anything.  Nothing should be using it.  SCM_MAX_FD is just an arbitrary
constant and it should be clear that its value is chosen in net/scm.h
and not actually derived from anything else meaningful in the system.
