Linux kernel source tree
0b3ad32e26
While testing recent discovery node rework, several items were seen that
could be done better with respect to the new trace event logic.
1) in the following msg:
kernel: lpfc 0000:44:00.0: start 35 end 35 cnt 0
If cnt is zero in the 1st message, there is no reason to display the
1st message, which is just giving start/end positioning.
Fix by not displaying message if cnt is 0.
2) If the driver is loaded with module log verbosity off, and later a
single NPIV host instance verbosity is enabled via sysfs, it enables
messages on all instances. This is due to the trace log verbosity checks
(lpfc_dmp_dbg) looking at the phba only. It should look at the phba and
the vport.
Fix by enabling a check on both phba and vport.
3) in the following messages:
2904 Firmware Dump Image Present on Adapter
2887 Reset Needed: Attempting Port Recovery...
These messages are not necessary for the trace event log, which is
primarily for discovery.
Fix by changing log level on these 2 messages to LOG_SLI.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
