    Subject[PATCH] [RESEND] fs: cachefiles: Add support for large files in filesystem caching
    The below patch which was first posted here:

    https://lkml.org/lkml/2012/4/3/193

    and tested by me and picked up by the maintainer here:

    https://lkml.org/lkml/2012/5/1/57

    But it seems to not to have made to the linux-next or Linus tree.
    I'm resending what it seems like a lost patch.


    From: Justin Lecher <jlec@gentoo.org>

    Support the caching of large files.
