* PR 9871 (partial) fix. Removed more embedded-C in nfs_proc.stp and nfs.stp.David Smith2010-04-061-42/+72
| | | | | | | | | | * tapset/nfs_proc.stp: Added script functions NFS_I(), NFS_FH(), NFS_SERVER, NFS_PROTO. Rewrote embedded-C functions __nfsv4_bitmask() and __getfh_inode() in script language. * tapset/nfs.stp: Rewrote embedded-C functions __nfsi_cache_valid(), __nfsi_rcache_time(), __nfsi_attr_time(), __nfsi_ndirty(), __nfs_server_rsize(), __nfs_version(), __nfs_server_wsize(), __nfs_rpages(), and __nfs_wpages() in script language.
* PR 9871 (partial) fix. Removed more embedded-C in nfs_proc.stp.David Smith2010-04-051-156/+92
| | | | | | | * tapset/nfs_proc.stp: Rewrote embedded-C functions stap_NFS_CLIENT(), get_ip_from_client(), get_prot_from_client(), get_ip(), and get_prot() in script language. Simplified __i2n_ip_proto() by just calling get_ip_from_client() or get_prot_from_client().
* PR 9871 (partial) fix. Removed some embedded-C in nfs_proc.stp.David Smith2010-04-051-22/+21
| | | | | * tapset/nfs_proc.stp: To avoid a deref hazard, rewrote embedded-C __i2n_ip_proto() in script language.
* PR 5150. Fixed nfs tapset by making probes optional.David Smith2009-11-181-22/+30
| | | | | | | * tapset/nfs_proc.stp: Made 'nfs.proc.read', 'nfs.proc.write', and 'nfs.proc.commit' optional for newer kernels without those functions. * testsuite/systemtap.pass1-4/buildok.exp: Expect nfs-all-probes.stp to pass.
* Tweak kernel or module resident probeWenji Huang2009-07-191-78/+78
| | | | | | * tapset/nfs_proc.stp: Change '?' notation to "!". * tapset/nfsd.stp: Ditto. * tapset/scsi.stp: Ditto.
* More gcc 4.5 'jump skips variable initialization' fixlets.Mark Wielaard2009-07-081-5/+11
| | | | | | | | | * tapset/ioblock.stp (__bio_start_sect): Declare, then initialize variables that could (through kread) take an early jump. * tapset/nfs_proc.stp (get_prot_from_client): Likewise. * tapset/scsi.stp (scsi_timer_pending): Likewise. * tapset/task.stp (task_cpu): Likewise. (task_open_file_handles): Likewise.
* Use 'static' as much as possibleJosh Stone2009-01-281-10/+10
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.
