  • e4eff1a62   SUNRPC: Clean up the sillyrename code ... Browse Code »

    Fix a couple of bugs:
    - Don't rely on the parent dentry still being valid when the call completes.
    Fixes a race with shrink_dcache_for_umount_subtree()

    - Don't remove the file if the filehandle has been labelled as stale.

    Fix a couple of inefficiencies
    - Remove the global list of sillyrenamed files. Instead we can cache the
    sillyrename information in the dentry->d_fsdata
    - Move common code from unlink_setup/unlink_done into fs/nfs/unlink.c

  • 89a09141d   [PATCH] nfs: fix congestion control ... Browse Code »

    The current NFS client congestion logic is severly broken, it marks the
    backing device congested during each nfs_writepages() call but doesn't
    mirror this in nfs_writepage() which makes for deadlocks. Also it
    implements its own waitqueue.

    Replace this by a more regular congestion implementation that puts a cap on
    the number of active writeback pages and uses the bdi congestion waitqueue.

    Also always use an interruptible wait since it makes sense to be able to
    SIGKILL the process even for mounts without 'intr'.

  • 4dc2eaecd   NFS: move NFS_DEBUG definition ... Browse Code »

    Trond, looks like the changes to include/linux/nfs_fs.h in 2.6.18
    that moved the #include's of sunrpc header files into the #ifdef __KERNEL__ block
    disabled nfs debugging for all nfs c file not including any sunrpc header.

    The following patch moves the definition down, right before its use
    for defining ifdebug.

  • cd9ae2b6a   [PATCH] NFS: Deal with failure of invalidate_inode_pages2() ... Browse Code »

    If invalidate_inode_pages2() fails, then it should in principle just be
    because the current process was signalled. In that case, we just want to
    ensure that the inode's page cache remains marked as invalid.

    Also add a helper to allow the O_DIRECT code to simply mark the page cache as
    invalid once it is finished writing, instead of calling
    invalidate_inode_pages2() itself.

  • 24c8dbbb5   NFS: Generalise the nfs_client structure ... Browse Code »

    Generalise the nfs_client structure by:

    (1) Moving nfs_client to a more general place (nfs_fs_sb.h).

    (2) Renaming its maintenance routines to be non-NFS4 specific.

    (3) Move those maintenance routines to a new non-NFS4 specific file (client.c)
    and move the declarations to internal.h.

    (4) Make nfs_find/get_client() take a full sockaddr_in to include the port
    number (will be required for NFS2/3).

    (5) Make nfs_find/get_client() take the NFS protocol version (again will be
    required to differentiate NFS2, 3 & 4 client records).

    Also:

    (6) Make nfs_client construction proceed akin to inodes, marking them as under
    construction and providing a function to indicate completion.

    (7) Make nfs_get_client() wait interruptibly if it finds a client that it can
    share, but that client is currently being constructed.

    (8) Make nfs4_create_client() use (6) and (7) instead of locking cl_sem.

    The current access cache only allows one entry at a time to be cached for each

    directories such as ${PATH}, /usr/share, etc.

  • 7f1cbe51f   [PATCH] headers_check: reduce user-visible noise in <linux/nfs_fs.h> ... Browse Code »

    We don't need any of this crap included from the user-visible part of nfs_fs.h
    -- remove it all.

    In fact, we probably don't need anything but NFS_SUPER_MAGIC to be defined; is
    there any need for anything else? And magic numbers should probably move to
    rather than being strewn across various fs-specific include
    files which exist in userspace for solely that purpose.

    With this patch, 'make header_check' works again at least on PowerPC.

  • e9f7bee1d   [PATCH] NFS: large non-page-aligned direct I/O clobbers memory ... Browse Code »

    The logic in nfs_direct_read_schedule and nfs_direct_write_schedule can
    allow data->npages to be one larger than rpages. This causes a page
    pointer to be written beyond the end of the pagevec in nfs_read_data (or
    nfs_write_data).

    Fix this by making nfs_(read|write)_alloc() calculate the size of the
    pagevec array, and initialise data->npages.

    Also get rid of the redundant argument to nfs_commit_alloc().

    Respond to a moved error on NFS lookup by setting up the referral.
    Note: We don't actually follow the referral during lookup/getattr, but
    later when we detect fsid mismatch in inode revalidation (similar to the
    processing done for cloning submounts). Referrals will have fake attributes
    until they are actually followed or traversed.
