  • bd238fb43   9p: Reorganization of 9p file system code ... Browse Code »

    This patchset moves non-filesystem interfaces of v9fs from fs/9p to net/9p.
    It moves the transport, packet marshalling and connection layers to net/9p
    leaving only the VFS related files in fs/9p. This work is being done in
    preparation for in-kernel 9p servers as well as alternate 9p clients (other
    than VFS).

  • e03abc0c9   9p: implement optional loose read cache ... Browse Code »

    While cacheing is generally frowned upon in the 9p world, it has its
    place -- particularly in situations where the remote file system is
    exclusive and/or read-only. The vacfs views of venti content addressable
    store are a real-world instance of such a situation. To facilitate higher
    performance for these workloads (and eventually use the fscache patches),
    we have enabled a "loose" cache mode which does not attempt to maintain
    any form of consistency on the page-cache or dcache. This results in over
    two orders of magnitude performance improvement for cacheable block reads
    in the Bonnie benchmark. The more aggressive use of the dcache also seems
    to improve metadata operational performance.

  • 4b6f5d20b   [PATCH] Make most file operations structs in fs/ const ... Browse Code »

    This is a conversion to make the various file_operations structs in fs/
    const. Basically a regexp job, with a few manual fixups

    The goal is both to increase correctness (harder to accidentally write to
    shared datastructures) and reducing the false sharing of cachelines with
    things that get dirty in .data (while .rodata is nicely read only and thus
    cache clean)

  • 6a3124a39   [PATCH] v9fs: fix atomic create open ... Browse Code »

    In order to assure atomic create+open v9fs stores the open fid produced by
    v9fs_vfs_create in the dentry, from where v9fs_file_open retrieves it and
    associates it with the open file.

    This patch modifies v9fs to use nameidata.intent.open values to do the atomic
    create+open.

  • 147b31cf0   [PATCH] v9fs: add readpage support ... Browse Code »

    v9fs mmap support was originally removed from v9fs at Al Viro's request,
    but recently there have been requests from folks who want readpage
    functionality (primarily to enable execution of files mounted via 9P).
    This patch adds readpage support (but not writepage which contained most of
    the objectionable code). It passes fsx-linux (and other regressions) so it
    should be relatively safe.
