From: Yehuda Sadeh Date: Tue, 6 Apr 2010 21:33:58 +0000 (-0700) Subject: ceph: all allocation functions should get gfp_mask X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=34d23762d988b7dcb08390ac72a353df3d60193c;p=linux-beck.git 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.
