From 8d6deb807efa1a4145df117a8b9b4a2c42ec333d Mon Sep 17 00:00:00 2001 From: Uma Krishnan Date: Fri, 11 May 2018 14:05:08 -0500 Subject: [PATCH] scsi: cxlflash: Limit the debug logs in the IO path The kernel log can get filled with debug messages from send_cmd_ioarrin() when dynamic debug is enabled for the cxlflash module and there is a lot of legacy I/O traffic. While these messages are necessary to debug issues that involve command tracking, the abundance of data can overwrite other useful data in the log. The best option available is to limit the messages that should serve most of the common use cases. Signed-off-by: Uma Krishnan Acked-by: Matthew R. Ochs Signed-off-by: Martin K.
