If you're running a kernel with a version - of relayfs >= 4 (the version # can be found in - /include/linux/relayfs_fs.h) configured in, adding a - #define RELAYFS_VERSION_GE_4 at the top of transport/relayfs.h - will make systemtap use it instead of the packaged version. - - * relayfs.c: Add ifdef'ed relayfs callback functions for - mainline relayfs version. - (_stp_relayfs_open): Add ifdef'ed code for mainline - relayfs version. - * procfs.c (_stp_proc_read): Ditto. - * transport.c (_handle_buf_info): Ditto. - -2005-10-05 Tom Zanussi <zanussi@us.ibm.com> - - * transport.c (_stp_transport_open): Add kbug message. - * transport.h: Change default n_subbufs to 16. - -2005-09-08 Martin Hunt <hunt@redhat.com> - - * procfs.c (_stp_register_procfs): Change ifdefs to eliminate - unused variable warnings. - (_stp_unregister_procfs): Ditto. - -2005-09-06 Martin Hunt <hunt@redhat.com> - - * transport.c (_stp_handle_start): Always reply to - a start message with STP_START. - -2005-08-24 Martin Hunt <hunt@redhat.com> - - * transport_msgs.h (enum): New type, STP_OOB_DATA. - -2005-08-23 Martin Hunt <hunt@redhat.com> - - * transport.c (_stp_cleanup_and_exit): Remove a 2 second sleep - that should no longer be necessary. - - * procfs.c (_stp_write): If the ready queue is not empty - then attempt to grab the last buffer in it and append our data - to it. - -2005-08-22 Martin Hunt <hunt@redhat.com> - - * transport.h: Don't define _stp_transport_write. - * transport.c (_stp_transport_write): Use - _stp_transport_send() when in probe_exit(). - -2005-08-19 Martin Hunt <hunt@redhat.com> - - * transport.c (_stp_cmd_handler): Remove. This was used by - stp-control. - - * procfs.c (_stp_proc_write_cmd): Call schedule_work() instead - of running _stp_exit_handler immediately. Fixes a problem where - the module couldn't exit if all the output buffers were full. - Set .owner for the filesystem entries. - -2005-08-19 Martin Hunt <hunt@redhat.com> - - * transport.h: Remove netlink references. - * transport.c: Remove netlink references.
