  • fd2421f54   fs/9p: When doing inode lookup compare qid details and inode mode bits. ... Browse Code »
    1

    This make sure we don't use wrong inode from the inode hash. The inode number
    of the file deleted is reused by the next file system object created
    and if we only use inode number for inode hash lookup we could end up
    with wrong struct inode.

    Also compare inode generation number. Not all Linux file system provide
    st_gen in userspace. So it could be 0;

  • a78ce05d5   fs/9p: Add v9fs_inode ... Browse Code »

    Switch to the fscache code to v9fs_inode. We will later use
    v9fs_inode in cache=loose mode to track the inode cache
    validity timeout. Ie if we find an inode in cache older
    that a specific jiffie range we will consider it stale

  • 60e78d2c9   9p: Add fscache support to 9p ... Browse Code »

    This patch adds a persistent, read-only caching facility for
    9p clients using the FS-Cache caching backend.

    When the fscache facility is enabled, each inode is associated
    with a corresponding vcookie which is an index into the FS-Cache
    indexing tree. The FS-Cache indexing tree is indexed at 3 levels:
    - session object associated with each mount.
    - inode/vcookie
    - actual data (pages)

    A cache tag is chosen randomly for each session. These tags can
    be read off /sys/fs/9p/caches and can be passed as a mount-time
    parameter to re-attach to the specified caching session.
