Subject: [PATCH 02/20] mm: Use vmf->address instead of of vmf->virtual_address
Date: Fri, 18 Nov 2016 10:17:06 +0100 [thread overview]
Message-ID: <1479460644-25076-3-git-send-email-jack@suse.cz> (raw)
In-Reply-To: <1479460644-25076-1-git-send-email-jack@suse.cz>
Every single user of vmf->virtual_address typed that entry to unsigned
long before doing anything with it so the type of virtual_address does
not really provide us any additional safety. Just use masked
vmf->address which already has the appropriate type.

Subject: [PATCH 02/20] mm: Use vmf->address instead of of vmf->virtual_address
Date: Fri, 18 Nov 2016 10:17:06 +0100 [thread overview]
Message-ID: <1479460644-25076-3-git-send-email-jack@suse.cz> (raw)
In-Reply-To: <1479460644-25076-1-git-send-email-jack@suse.cz>
Every single user of vmf->virtual_address typed that entry to unsigned
long before doing anything with it so the type of virtual_address does
not really provide us any additional safety. Just use masked
vmf->address which already has the appropriate type.
