  • a447c0932   vfs: Use const for kernel parser table ... Browse Code »

    This is a much better version of a previous patch to make the parser
    tables constant. Rather than changing the typedef, we put the "const" in
    all the various places where its required, allowing the __initconst
    exception for nfsroot which was the cause of the previous trouble.

    This was posted for review some time ago and I believe its been in -mm
    since then.

  • 529ae9aaa   mm: rename page trylock ... Browse Code »

    Converting page lock to new locking bitops requires a change of page flag
    operation naming, so we might as well convert it to something nicer
    (!TestSetPageLocked_Lock => trylock_page, SetPageLocked => set_page_locked).

    This also facilitates lockdeping of page lock.

  • 4ac913785   Embed a struct path into struct nameidata instead of nd->{dentry,mnt} ... Browse Code »

    This is the central patch of a cleanup series. In most cases there is no good
    reason why someone would want to use a dentry for itself. This series reflects
    that fact and embeds a struct path into nameidata.

    Together with the other patches of this series
    - it enforced the correct order of getting/releasing the reference count on
    pairs
    - it prepares the VFS for stacking support since it is essential to have a
    struct path in every place where the stack can be traversed
    - it reduces the overall code size:

    without patch series:
    text data bss dec hex filename
    5321639 858418 715768 6895825 6938d1 vmlinux

    with patch series:
    text data bss dec hex filename
    5320026 858418 715768 6894212 693284 vmlinux

    This patch:

    Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

  • 7a224228e   vfs: Add 64 bit i_version support ... Browse Code »

    The i_version field of the inode is changed to be a 64-bit counter that
    is set on every inode creation and that is incremented every time the
    inode data is modified (similarly to the "ctime" time-stamp).
    The aim is to fulfill a NFSv4 requirement for rfc3530.
    This first part concerns the vfs, it converts the 32-bit i_version in
    the generic inode to a 64-bit, a flag is added in the super block in
    order to check if the feature is enabled and the i_version is
    incremented in the vfs.

  • 76181c134   KEYS: Make request_key() and co fundamentally asynchronous ... Browse Code »

    Make request_key() and co fundamentally asynchronous to make it easier for
    NFS to make use of them. There are now accessor functions that do
    asynchronous constructions, a wait function to wait for construction to
    complete, and a completion function for the key type to indicate completion
    of construction.

    Note that the construction queue is now gone. Instead, keys under
    construction are linked in to the appropriate keyring in advance, and that
    anyone encountering one must wait for it to be complete before they can use
    it. This is done automatically for userspace.

    The following auxiliary changes are also made:

    (1) Key type implementation stuff is split from linux/key.h into
    linux/key-type.h.

    (2) AF_RXRPC provides a way to allocate null rxrpc-type keys so that AFS does
    not need to call key_instantiate_and_link() directly.

    (3) Adjust the debugging macros so that they're -Wformat checked even if
    they are disabled, and make it so they can be enabled simply by defining
    __KDEBUG to be consistent with other code of mine.

    (3) Documentation.

  • 881d966b4   [NET]: Make the device list and device lookups per namespace. ... Browse Code »

    This patch makes most of the generic device layer network
    namespace safe. This patch makes dev_base_head a
    network namespace variable, and then it picks up
    a few associated variables. The functions:
    dev_getbyhwaddr
    dev_getfirsthwbytype
    dev_get_by_flags
    dev_get_by_name
    __dev_get_by_name
    dev_get_by_index
    __dev_get_by_index
    dev_ioctl
    dev_ethtool
    dev_load
    wireless_process_ioctl

    were modified to take a network namespace argument, and
    deal with it.

    vlan_ioctl_set and brioctl_set were modified so their
    hooks will receive a network namespace argument.

    So basically anthing in the core of the network stack that was
    affected to by the change of dev_base was modified to handle
    multiple network namespaces. The rest of the network stack was
    simply modified to explicitly use &init_net the initial network
    namespace. This can be fixed when those components of the network
    stack are modified to handle multiple network namespaces.

    For now the ifindex generator is left global.

    Fundametally ifindex numbers are per namespace, or else
    we will have corner case problems with migration when
    we get that far.

    At the same time there are assumptions in the network stack
    that the ifindex of a network device won't change. Making
    the ifindex number global seems a good compromise until
    the network stack can cope with ifindex changes when
    you change namespaces, and the like.

    (*) Made the locking non-fair: New readlocks will jump pending writelocks if

    similar to Linux's VFS locking.
