            Bug ID: 17690
           Summary: probe nfs.proc3.rename no longer valid
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tapsets
          Assignee: systemtap at sourceware dot org
          Reporter: dsmith at redhat dot com

Under newer kernels, the nfs.proc3.rename probe is broken:

====
# stap -ve 'probe nfs.proc3.rename {}'
Pass 1: parsed user script and 109 library script(s) using
216584virt/32080res/2984shr/29532data kb, in 210usr/50sys/255real ms.
semantic error: while resolving probe point: identifier 'nfs' at <input>:1:7
        source: probe nfs.proc3.rename {}
====

This is because the kernel switched to an asynchronous rename method then
finally removed the old code that systemtap probed in this commit:

====
commit 33912be816d96e204ed7a93690552daa39c08ea9

    nfs: remove synchronous rename code                                         

    Now that nfs_rename uses the async infrastructure, we can remove this.

This commit is first present in kernel 3.15.

Fixed in commit 1b438c7. Note that the probe nfs.proc4.rename was also no
longer valid. I also updated the argument name in several probes.
