Subject: [PATCH 5/8] [SCSI] tgt: Pass pointers to virt_to_page(), not integers
Date: Wed, 21 Dec 2011 01:34:20 +0000 [thread overview]
Message-ID: <1324431260.2844.150.camel@deadeye> (raw)
In-Reply-To: <1324430940.2844.144.camel@deadeye>
Most architectures define virt_to_page() as a macro that casts its
argument such that an argument of type unsigned long will be accepted
without complaint. However, the proper type is void *, and passing
unsigned long results in a warning on MIPS.
