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_eq_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.
