[DTrace-devel] [PATCH] test: skip when /proc/kallmodsyms is not present

[Eugene Loh]

I'm rusty on this stuff, but maybe you can help me out.  What happens 
with the test if kallmodsyms is not there?  The test does not directly 
rely on that file.  The test simply makes libdtrace calls, and 
dt_modsym_update() can fail over to kallsyms if kallmodsyms is not present.
