  • 2451337dd   xfs: global error sign conversion ... Browse Code »

    Convert all the errors the core XFs code to negative error signs
    like the rest of the kernel and remove all the sign conversion we
    do in the interface layers.

    Errors for conversion (and comparison) found via searches like:

    $ git grep " E" fs/xfs
    $ git grep "return E" fs/xfs
    $ git grep " E[A-Z].*;$" fs/xfs

    Negation points found via searches like:

    $ git grep "= -[a-z,A-Z]" fs/xfs
    $ git grep "return -[a-z,A-D,F-Z]" fs/xfs
    $ git grep " -[a-z].*;" fs/xfs

    [ with some bits I missed from Brian Foster ]

  • a4fbe6ab1   xfs: decouple inode and bmap btree header files ... Browse Code »

    Currently the xfs_inode.h header has a dependency on the definition
    of the BMAP btree records as the inode fork includes an array of
    xfs_bmbt_rec_host_t objects in it's definition.

    Move all the btree format definitions from xfs_btree.h,
    xfs_bmap_btree.h, xfs_alloc_btree.h and xfs_ialloc_btree.h to
    xfs_format.h to continue the process of centralising the on-disk
    format definitions. With this done, the xfs inode definitions are no
    longer dependent on btree header files.

    The enables a massive culling of unnecessary includes, with close to
    200 #include directives removed from the XFS kernel code base.

  • fdd3cceef   xfs: factor all the kmalloc-or-vmalloc fallback allocations ... Browse Code »

    We have quite a few places now where we do:

    x = kmem_zalloc(large size)
    if (!x)
    x = kmem_zalloc_large(large size)

    and do a similar dance when freeing the memory. kmem_free() already
    does the correct freeing dance, and kmem_zalloc_large() is only ever
    called in these constructs, so just factor it all into
    kmem_zalloc_large() and kmem_free().

  • 9356fe22a   xfs: make struct xfs_perag kernel only ... Browse Code »

    The struct xfs_perag has many kernel-only definitions in it,
    requiring a __KERNEL__ guard so userspace can use it to. Move it to
    xfs_mount.h so that it it kernel-only, and let userspace redefine
    it's own version of the structure containing only what it needs.
    This gets rid of another __KERNEL__ check in the XFS header files.

  • c24b5dfad   xfs: kill xfs_vnodeops.[ch] ... Browse Code »

    Now we have xfs_inode.c for holding kernel-only XFS inode
    operations, move all the inode operations from xfs_vnodeops.c to
    this new file as it holds another set of kernel-only inode
    operations. The name of this file traces back to the days of Irix
    and it's vnodes which we don't have anymore.

    Essentially this move consolidates the inode locking functions
    and a bunch of XFS inode operations into the one file. Eventually
    the high level functions will be merged into the VFS interface
    functions in xfs_iops.c.

    This leaves only internal preallocation, EOF block manipulation and
    hole punching functions in vnodeops.c. Move these to xfs_bmap_util.c
    where we are already consolidating various in-kernel physical extent
    manipulation and querying functions.

    The transaction reservation size calculations is used by both kernel
    and userspace, but most of the transaction code in xfs_trans.c is
    kernel specific. Split all the transaction reservation code out into
    it's own files to make sharing with userspace simpler. This just
    leaves kernel-only definitions in xfs_trans.h, so it doesn't need to
    be shared with userspace anymore, either.

  • 5f3a4a28e   userns: Pass a userns parameter into posix_acl_to_xattr and posix_acl_from_xattr ... Browse Code »

    - Pass the user namespace the uid and gid values in the xattr are stored
    in into posix_acl_from_xattr.

    - Pass the user namespace kuid and kgid values should be converted into
    when storing uid and gid values in an xattr in posix_acl_to_xattr.

    - Modify all callers of posix_acl_from_xattr and posix_acl_to_xattr to
    pass in &init_user_ns.

    In the short term this change is not strictly needed but it makes the
    code clearer. In the longer term this change is necessary to be able to
    mount filesystems outside of the initial user namespace that natively
    store posix acls in the linux xattr format.

    This patch rips out the XFS ACL handling code and uses the generic
    fs/posix_acl.c code instead. The ondisk format is of course left
    unchanged.

    This also introduces the same ACL caching all other Linux filesystems do
    by adding pointers to the acl and default acl in struct xfs_inode.
