From 08358906ed78f6ab4d3ff8e4fd1b87b9a4aea645 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 4 Jul 2012 10:54:47 -0400 Subject: [PATCH] xfs: remove the alloc_done argument to xfs_dialloc We can simplify check the IO_agbp pointer for being non-NULL instead of passing another argument through two layers of function calls.
