* spinlock to internal buffers before writing.

* Lock ordering (including related VFS locks) is the following:
- * i_mutex > dqonoff_sem > journal_lock > dqptr_sem > dquot->dq_lock >
+ * dqonoff_mutex > i_mutex > journal_lock > dqptr_sem > dquot->dq_lock >
* dqio_mutex
+ * dqonoff_mutex > i_mutex comes from dquot_quota_sync, dquot_enable, etc.
* The lock ordering of dqptr_sem imposed by quota code is only dqonoff_sem >
* dqptr_sem. But filesystem has to count with the fact that functions such as
* dquot_alloc_space() acquire dqptr_sem and they usually have to be called
* from inside a transaction to keep filesystem consistency after a crash. Also
* filesystems usually want to do some IO on dquot from ->mark_dirty which is
* called with dqptr_sem held.
- * i_mutex on quota files is special (it's below dqio_mutex)
