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Summary: probe nfs.proc3.rename no longer valid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:

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.
