            Bug ID: 18000
           Summary: kernel tracepoints not found without using the cache
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: dsmith at redhat dot com

On 3.18.3-201.fc21.x86_64 with HEAD systemtap, I'm seeing this:

====
# rm -rf ~/.systemtap/cache
# stap --disable-cache -p4 -e 'probe kernel.trace("net_dev_queue") { exit() }'
semantic error: while resolving probe point: identifier 'kernel' at <input>:1:7
        source: probe kernel.trace("net_dev_queue") { exit() }
                      ^

semantic error: no match

Pass 2: analysis failed.  [man error::pass2]
# stap -p4 -e 'probe kernel.trace("net_dev_queue") { exit() }'

So, if you disable the cache, the net_dev_queue tracepoint cannot be found. The
same thing happens if you use 'net:net_dev_queue":

====
# rm -rf ~/.systemtap/cache/
# stap --disable-cache -p4 -e 'probe kernel.trace("net:net_dev_queue") { exit()
}'
semantic error: while resolving probe point: identifier 'kernel' at <input>:1:7
        source: probe kernel.trace("net:net_dev_queue") { exit() }
                      ^

semantic error: no match

Pass 2: analysis failed.  [man error::pass2]
# stap -p4 -e 'probe kernel.trace("net:net_dev_queue") { exit() }'
