From b43fa8284d7790d9cca32c9c55e24f29be2fa33b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 3 Mar 2010 09:05:03 -0500 Subject: dquot: cleanup dquot transfer routine Get rid of the transfer dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_transfer helper to __dquot_transfer and vfs_dq_transfer to dquot_transfer to have a consistent namespace, and make the new dquot_transfer return a normal negative errno value which all callers expect.
