Subject: [PATCH v4 14/23] ncr5380: Reduce max_lun limit
Date: Wed, 23 Mar 2016 21:10:23 +1100 [thread overview]
Message-ID: <20160323101012.921725572@telegraphics.com.au> (raw)
In-Reply-To: 20160323101009.341929635@telegraphics.com.au
[-- Attachment #1: ncr5380-max_lun --]
[-- Type: text/plain, Size: 995 bytes --]
The driver has a limit of eight LUs because of the byte-sized bitfield
that is used for busy flags. That means the maximum LUN is 7. The default
is 8.

Changed since v1:
- Reduce shost->max_lun limit instead of adding 'MAX_LUN' limit.
