	Instead of open coding a __dynamic_array() with a fixed length (which defeats the purpose of the dynamic array in the first place). Use the new __vstring() helper that will use a va_list and only write enough of the string into the ring buffer that is needed.

2018-12-21	scsi: iscsi: Capture iscsi debug messages using tracepoints	Fred Herard	1	-0/+107
	This commit enhances iscsi initiator modules to capture iscsi debug messages using linux kernel tracepoint facility: https://www.kernel.org/doc/Documentation/trace/tracepoints.txt The following tracepoint events have been created under the iscsi tracepoint event group: iscsi_dbg_conn - to capture connection debug messages (libiscsi module) iscsi_dbg_session - to capture session debug messages (libiscsi module) iscsi_dbg_eh - to capture error handling debug messages (libiscsi module) iscsi_dbg_tcp - to capture iscsi tcp debug messages (libiscsi_tcp module) iscsi_dbg_sw_tcp - to capture iscsi sw tcp debug messages (iscsi_tcp module) iscsi_dbg_trans_session - to cpature iscsi transsport sess debug messages (scsi_transport_iscsi module) iscsi_dbg_trans_conn - to capture iscsi transport conn debug messages (scsi_transport_iscsi module) [mkp: typos] Signed-off-by: Fred Herard <fred.herard@oracle.com> Reviewed-by: Rajan Shanmugavelu <rajan.shanmugavelu@oracle.com> Reviewed-by: Lee Duncan <lduncan@suse.com> Reviewed-by: Douglas Gilbert <dgilbert@interlog.com> Signed-off-by: Martin K.
