Description Frank Ch. Eigler 2019-07-02 16:09:56 UTC
probe aliases like nfsd.close do not work after kernel has renamed/moved around nfsd_* functions.

Comment 2 Frank Ch. Eigler 2020-04-14 20:19:29 UTC
the kernel no longer gives us a convenient point to mark the release of an nfsd file handle (just an fput).  The kernel tracepoints nfsd:nfsd_file_put and nfsd_file_put_final are probably the closest thing, but they require kernel SOURCES (since the nfsd tracepoint header files are not installed into kernel-devel).
