Subject: [patch 09/10] mm: bootmem: pass pgdat instead of pgdat->bdata down the stack
Date: Mon, 7 May 2012 13:37:51 +0200 [thread overview]
Message-ID: <1336390672-14421-10-git-send-email-hannes@cmpxchg.org> (raw)
In-Reply-To: <1336390672-14421-1-git-send-email-hannes@cmpxchg.org>
Pass down the node descriptor instead of the more specific bootmem
node descriptor down the call stack, like nobootmem does, when there
is no good reason for the two to be different.
