+/*
+ * Locking of quotas with OCFS2 is rather complex. Here are rules that
+ * should be obeyed by all the functions:
+ * - any write of quota structure (either to local or global file) is protected
+ * by dqio_mutex or dquot->dq_lock.
+ * - any modification of global quota file holds inode cluster lock, i_mutex,
+ * and ip_alloc_sem of the global quota file (achieved by
+ * ocfs2_lock_global_qf). It also has to hold qinfo_lock.
+ * - an allocation of new blocks for local quota file is protected by
+ * its ip_alloc_sem
+ *
+ * A rough sketch of locking dependencies (lf = local file, gf = global file):
+ * Normal filesystem operation:
+ * start_trans -> dqio_mutex -> write to lf
+ * Syncing of local and global file:
+ * ocfs2_lock_global_qf -> start_trans -> dqio_mutex -> qinfo_lock ->
+ * write to gf
+ * -> write to lf
+ * Acquire dquot for the first time:
+ * dq_lock -> ocfs2_lock_global_qf -> qinfo_lock -> read from gf
+ * -> alloc space for gf
+ * -> start_trans -> qinfo_lock -> write to gf
+ * -> ip_alloc_sem of lf -> alloc space for lf
+ * -> write to lf
+ * Release last reference to dquot:
+ * dq_lock -> ocfs2_lock_global_qf -> start_trans -> qinfo_lock -> write to gf
+ * -> write to lf
+ * Note that all the above operations also hold the inode cluster lock of lf.
+ * Recovery:
+ * inode cluster lock of recovered lf
+ * -> read bitmaps -> ip_alloc_sem of lf
+ * -> ocfs2_lock_global_qf -> start_trans -> dqio_mutex -> qinfo_lock ->
+ * write to gf
