[PATCH AUTOSEL 6.10 64/70] scsi: lpfc: Revise TRACE_EVENT log flag severities from KERN_ERR to KERN_WARNING
From: Sasha Levin
Date: Fri Oct 04 2024 - 14:56:35 EST
From: Justin Tee <justin.tee@xxxxxxxxxxxx>
[ Upstream commit 1af9af1f8ab38f1285b27581a5e6920ec58296ba ]
Revise certain log messages marked as KERN_ERR LOG_TRACE_EVENT to
KERN_WARNING and use the lpfc_vlog_msg() macro to still log the event. The
benefit is that events of interest are still logged and the entire trace
buffer is not dumped with extraneous logging information when using default
lpfc_log_verbose driver parameter settings.
Also, delete the keyword "fail" from such log messages as they aren't
really causes for concern. The log messages are more for warnings to a SAN
admin about SAN activity.
