[PATCH 8/8] dquot: cleanup dquot initialize routine

[Christoph Hellwig <hch@infradead.org>]

[-- Attachment #1: quota-kill-initialize --]
[-- Type: text/plain, Size: 38653 bytes --]

Get rid of the initialize 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_initialize helper to __dquot_initialize
and vfs_dq_init to dquot_initialize to have a consistent namespace.

Signed-off-by: Christoph Hellwig <hch@lst.de>
