++ * The quota code uses five lists for dquot management: the inuse_list,

++ * A single dquot structure may be on some of those lists, depending on
++ * its current state.
+ *
+ * All dquots are placed to the end of inuse_list when first created, and this
+ * list is used for invalidate operation, which must look at every dquot.
+ *
++ * When the last reference of a dquot will be dropped, the dquot will be
++ * added to releasing_dquots. We'd then queue work item which would call
++ * synchronize_srcu() and after that perform the final cleanup of all the
++ * dquots on the list. Both releasing_dquots and free_dquots use the
++ * dq_free list_head in the dquot struct. When a dquot is removed from
++ * releasing_dquots, a reference count is always subtracted, and if
++ * dq_count == 0 at that point, the dquot will be added to the free_dquots.
++ *
+ * Unused dquots (dq_count == 0) are added to the free_dquots list when freed,
+ * and this list is searched whenever we need an available dquot. Dquots are
+ * removed from the list as soon as they are used again, and
+ * dqstats.free_dquots gives the number of dquots on the list. When
+ * dquot is invalidated it's completely released from memory.
+ *
++ * Dirty dquots are added to the dqi_dirty_list of quota_info when mark
++ * dirtied, and this list is searched when writing dirty dquots back to
++ * quota file. Note that some filesystems do dirty dquot tracking on their
++ * own (e.g. in a journal) and thus don't use dqi_dirty_list.

+ * Dquots with a specific identity (device, type and id) are placed on

+-/*
+- Comparing to general packet classification problem,
+- RSVP needs only sevaral relatively simple rules:
+-
+- * (dst, protocol) are always specified,
+- so that we are able to hash them.
+- * src may be exact, or may be wildcard, so that
+- we can keep a hash table plus one wildcard entry.
+- * source port (or flow label) is important only if src is given.
+-
+- IMPLEMENTATION.
+-
+- We use a two level hash table: The top level is keyed by
+- destination address and protocol ID, every bucket contains a list
+- of "rsvp sessions", identified by destination address, protocol and
+- DPI(="Destination Port ID"): triple (key, mask, offset).
+-
+- Every bucket has a smaller hash table keyed by source address
+- (cf. RSVP flowspec) and one wildcard entry for wildcard reservations.
+- Every bucket is again a list of "RSVP flows", selected by
+- source address and SPI(="Source Port ID" here rather than
+- "security parameter index"): triple (key, mask, offset).
+-
+-
+- NOTE 1. All the packets with IPv6 extension headers (but AH and ESP)
+- and all fragmented packets go to the best-effort traffic class.
+-
+-
+- NOTE 2. Two "port id"'s seems to be redundant, rfc2207 requires
+- only one "Generalized Port Identifier". So that for classic
+- ah, esp (and udp,tcp) both *pi should coincide or one of them
+- should be wildcard.
+-
+- At first sight, this redundancy is just a waste of CPU
+- resources. But DPI and SPI add the possibility to assign different
+- priorities to GPIs. Look also at note 4 about tunnels below.
+-
+-
+- NOTE 3. One complication is the case of tunneled packets.
+- We implement it as following: if the first lookup
+- matches a special session with "tunnelhdr" value not zero,
+- flowid doesn't contain the true flow ID, but the tunnel ID (1...255).
+- In this case, we pull tunnelhdr bytes and restart lookup
+- with tunnel ID added to the list of keys. Simple and stupid 8)8)
+- It's enough for PIMREG and IPIP.
+-
+-
+- NOTE 4. Two GPIs make it possible to parse even GRE packets.
+- F.e. DPI can select ETH_P_IP (and necessary flags to make
+- tunnelhdr correct) in GRE protocol field and SPI matches
+- GRE key. Is it not nice? 8)8)
+-
+-
+- Well, as result, despite its simplicity, we get a pretty
+- powerful classification engine. */
