From 34d23762d988b7dcb08390ac72a353df3d60193c Mon Sep 17 00:00:00 2001 From: Yehuda Sadeh Date: Tue, 6 Apr 2010 14:33:58 -0700 Subject: ceph: all allocation functions should get gfp_mask This is essential, as for the rados block device we'll need to run in different contexts that would need flags that are other than GFP_NOFS.
