From db18efac0bd644e4b7af757394ca0bef8d91dcee Mon Sep 17 00:00:00 2001 From: Jaak Ristioja Date: Fri, 15 Jan 2010 12:05:07 +0200 Subject: bio: Fix outdated comment about bio_alloc_bioset() In commit 451a9ebf653d28337ba53ed5b4b70b0b9543cca1 bio_alloc_bioset() was refactored not to take NULL as a valid argument for bs. This patch changes the comment for that function accordingly. Currently, passing NULL as argument to parameter bs would result in a NULL pointer dereference.
