Looks like this comes from 2 example scripts (or would if you got the error
more than once):
general/para-callgraph.stp
general/para-callgraph-verbose.stp
The testcase for both of these does something like the following:
# stap para-callgraph.stp 'kernel.function("*@fs/proc*.c")'
'kernel.function("vfs_read")' -c "cat /proc/sys/vm/* || true"
If a process reads /proc/sys/vm/scan_unevictable_pages, that warning is
generated. On a freshly rebooted rawhide system with that kernel, just doing
the following by hand will cause that warning to appear:
# cat /proc/sys/vm/scan_unevictable_pages
Our options here are to ignore the warning or read a different set of files,
perhaps something in the testsuite directory itself.
