Subject: [PATCH v2 14/22] ncr5380: Reduce max_lun limit
Date: Wed, 16 Mar 2016 14:18:55 +1100 [thread overview]
Message-ID: <20160316031845.451670102@telegraphics.com.au> (raw)
In-Reply-To: 20160316031841.911913894@telegraphics.com.au
[-- Attachment #1: ncr5380-max_lun --]
[-- Type: text/plain, Size: 848 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.
Signed-off-by: Finn Thain <fthain@telegraphics.com.au>

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