From adae52b94e18afa1f84fab67df2a8a872c2f5533 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Thu, 31 Mar 2011 09:43:23 +0000 Subject: btrfs: clear __GFP_FS flag in the space cache inode the object id of the space cache inode's key is allocated from the relative root, just like the regular file. So we can't identify space cache inode by checking the object id of the inode's key, and we have to clear __GFP_FS flag at the time we look up the space cache inode.
