+/*
+ * The inode->i_version field:
+ * ---------------------------
+ * The change attribute (i_version) is mandated by NFSv4 and is mostly for
+ * knfsd, but is also used for other purposes (e.g. IMA). The i_version must
+ * appear different to observers if there was a change to the inode's data or
+ * metadata since it was last queried.
+ *
+ * Observers see the i_version as a 64-bit number that never decreases. If it
+ * remains the same since it was last checked, then nothing has changed in the
+ * inode. If it's different then something has changed. Observers cannot infer
+ * anything about the nature or magnitude of the changes from the value, only
+ * that the inode has changed in some fashion.
+ *
+ * Not all filesystems properly implement the i_version counter. Subsystems that
+ * want to use i_version field on an inode should first check whether the
+ * filesystem sets the SB_I_VERSION flag (usually via the IS_I_VERSION macro).
+ *
+ * Those that set SB_I_VERSION will automatically have their i_version counter
+ * incremented on writes to normal files. If the SB_I_VERSION is not set, then
+ * the VFS will not touch it on writes, and the filesystem can use it how it
+ * wishes. Note that the filesystem is always responsible for updating the
+ * i_version on namespace changes in directories (mkdir, rmdir, unlink, etc.).
+ * We consider these sorts of filesystems to have a kernel-managed i_version.
+ *
+ * It may be impractical for filesystems to keep i_version updates atomic with
+ * respect to the changes that cause them.  They should, however, guarantee
+ * that i_version updates are never visible before the changes that caused
+ * them.  Also, i_version updates should never be delayed longer than it takes
+ * the original change to reach disk.
+ *
+ * This implementation uses the low bit in the i_version field as a flag to
+ * track when the value has been queried. If it has not been queried since it
+ * was last incremented, we can skip the increment in most cases.
+ *
+ * In the event that we're updating the ctime, we will usually go ahead and
+ * bump the i_version anyway. Since that has to go to stable storage in some
+ * fashion, we might as well increment it as well.
+ *
+ * With this implementation, the value should always appear to observers to
+ * increase over time if the file has changed. It's recommended to use
+ * inode_cmp_iversion() helper to compare values.
+ *
+ * Note that some filesystems (e.g. NFS and AFS) just use the field to store
+ * a server-provided value (for the most part). For that reason, those
+ * filesystems do not set SB_I_VERSION. These filesystems are considered to
+ * have a self-managed i_version.
+ *
+ * Persistently storing the i_version
+ * ----------------------------------
+ * Queries of the i_version field are not gated on them hitting the backing
+ * store. It's always possible that the host could crash after allowing
+ * a query of the value but before it has made it to disk.
+ *
+ * To mitigate this problem, filesystems should always use
+ * inode_set_iversion_queried when loading an existing inode from disk. This
+ * ensures that the next attempted inode increment will result in the value
+ * changing.
+ *
+ * Storing the value to disk therefore does not count as a query, so those
+ * filesystems should use inode_peek_iversion to grab the value to be stored.
+ * There is no need to flag the value as having been queried in that case.
+ */
+
+/*
+ * We borrow the lowest bit in the i_version to use as a flag to tell whether
+ * it has been queried since we last incremented it. If it has, then we must
+ * increment it on the next change. After that, we can clear the flag and
+ * avoid incrementing it again until it has again been queried.
