* Backport recently added probes to RHEL5(U5)Steve Dickson2010-03-161-50/+69
| | | | | | | | Ensured the recent additions of v4 probes and supporting routines worked or at least don't break with RHEL5 U5 kernels (this time without kernel version checks). Signed-off-by: Steve Dickson <steved@redhat.com>

* Incorporated comments from code reviewSteve Dickson2010-03-161-40/+53
| | | | | | | | - Fixed a couple typos - To allow better optimization, removed the used of "convenience variables" Signed-off-by: Steve Dickson <steved@redhat.com>
* Allow better filtering with IP address and File handleSteve Dickson2010-03-161-23/+98
| | | | | | | | | | | | | | | To allow filtering by the client's IP address, the addr_from_rqst_str() function was added which extracts the IP address from incoming procedures and converts them into a character string. Calls to addr_from_rqst_str() were added to the top of each probe so callers of the probes can use the IP addresses as a filter. Calls to __svc_fh() were also sprinkled were needed so callers can also filter on file handles Signed-off-by: Steve Dickson <steved@redhat.com>
