  • 7394daa8c   FS-Cache: Add use of /proc and presentation of statistics ... Browse Code »

    Make FS-Cache create its /proc interface and present various statistical
    information through it. Also provide the functions for updating this
    information.

    These features are enabled by:

    CONFIG_FSCACHE_PROC
    CONFIG_FSCACHE_STATS
    CONFIG_FSCACHE_HISTOGRAM

    The /proc directory for FS-Cache is also exported so that caching modules can
    add their own statistics there too.

    The FS-Cache module is loadable at this point, and the statistics files can be
    examined by userspace:

    cat /proc/fs/fscache/stats
    cat /proc/fs/fscache/histogram

  • 0dfc41d1e   FS-Cache: Add the FS-Cache cache backend API and documentation ... Browse Code »

    Add the API for a generic facility (FS-Cache) by which caches may declare them
    selves open for business, and may obtain work to be done from network
    filesystems. The header file is included by:

    #include

    Documentation for the API is also added to:

    Documentation/filesystems/caching/backend-api.txt

    This API is not usable without the implementation of the utility functions
    which will be added in further patches.
