    Subject[PATCH take 3] UBIFS - new flash file system
    Date
    Hello,

    here is the third round of UBIFS submission. If you are not aware what
    UBIFS is about, please refer Jonathan Corbet's article:
    http://lwn.net/Articles/276025/

    Also, please refer the second and the first UBIFS submissions which
    contain short UBIFS description and URLs.
    second: http://marc.info/?l=linux-kernel&m=121006384211288&w=2
    first: http://marc.info/?l=linux-kernel&m=120662475821992&w=2

    We've addressed most of the requests from the second round:

    * Requests from Christoph Hellwig's review (may be found here:
    http://marc.info/?l=linux-kernel&m=121093446502796&w=2). Few things
    related to the background thread were not done though. Here are
    explanations why: http://marc.info/?l=linux-kernel&m=121155640026661&w=2
    and http://marc.info/?l=linux-kernel&m=121119680522445&w=2 (see end
    of the mail).
    Also, we have not changed readdir() implementation so far, but just
    put a comment that we cannot support NFS at the moment. However, we
    have an idea how to fix this, but need some comments from the community.
    We'll send a separate mail describing the problem and the possible
    solution shortly. Nevertheless, this should not be a blocker.
    * The 'generic_sync_sb_inodes()' was introduce as it was pointed to by
    Andrew Morton.
    * Many build fixes spotted by Andrew Morton.
    * Get rid of some dead code spotted by Marcin Slusarz.

    Other news is that UBIFS has been sitting in -mm tree for a couple of
    weeks already. And of course we have got more bug reports and fixed
    more bugs since the last submission.

    Christoph prefers tarballs - here it is:
    http://www.infradead.org/~dedekind/ubifs/ubifs-08-05-26.tar.bz2

    Changes between take 1 and take 2:
    * Store milliseconds for [mca]time stamps in the inodes, not only seconds
    (requested by Andi Kleen)
    * Documentation/filesystems/ubifs.txt has been added (requested by Josh Boyer)
    * do_div() is not anymore used with 'unsigned long long' values
    (requested by Andrew Morton)
    * The amount of debugging-related config options was lessened and module
    parameters were introduced instead (requested by Pekka Enberg and
    Christoph Hellwig)
    * Many assertions were removed (requested by Pekka Enberg)
    * Some debugging checks like custom memory leak and memory pressure checks
    were removed (requested by Pekka Enberg)

    Thank you,
    Adrian Hunter
    Artem Bityutskiy

    P.S. The patches are against v2.6.26-rc3.
