  • 2b1844a8c   UBIFS: introduce helper functions for debugging checks and tests ... Browse Code »

    This patch introduces helper functions for all debugging checks, so instead of
    doing

    if (!(ubifs_chk_flags & UBIFS_CHK_GEN))

    we now do

    if (!dbg_is_chk_gen(c))

    This is a preparation to further changes where the flags will go away, and
    we'll need to only change the helper functions, but the code which utilizes
    them won't be touched.

    At the same time this patch removes 'dbg_force_in_the_gaps()',
    'dbg_force_in_the_gaps_enabled()', and dbg_failure_mode helpers for
    consistency.

  • 376624476   UBIFS: use correct flags in lprops ... Browse Code »

    The UBIFS lpt tree is in many aspects similar to the TNC tree, and we have
    similar flags for these trees. And by mistake we use the COW_ZNODE flag for
    LPT in some places, instead of the right flag COW_CNODE. And this works
    only because these two constants have the same value.

    This patch makes all the LPT code to use COW_CNODE and also changes COW_CNODE
    constant value to make sure we do not misuse the flags any more.

  • fc5e58c0c   UBIFS: use GFP_NOFS properly ... Browse Code »

    This patch fixes a brown-paperbag bug which was introduced by me:
    I used incorrect "GFP_KERNEL | GFP_NOFS" allocation flags to make
    sure my allocations do not cause write-back. But the correct form
    is "GFP_NOFS".

  • cd5f7485b   UBIFS: allocate scanning buffer on demand ... Browse Code »

    Instead of using pre-allocated 'c->dbg->buf' buffer in
    'scan_check_cb()', dynamically allocate it when needed. The intend
    is to get rid of the pre-allocated 'c->dbg->buf' buffer and save
    128KiB of RAM (or more if PEB size is larger). Indeed, currently we
    allocate this memory even if the user never enables any self-check,
    which is wasteful.

  • 348709bad   UBIFS: do not print scary error messages needlessly ... Browse Code »

    At the moment UBIFS print large and scary error messages and
    flash dumps in case of nearly any corruption, even if it is
    a recoverable corruption. For example, if the master node is
    corrupted, ubifs_scan() prints error dumps, then UBIFS recovers
    just fine and goes on.

    This patch makes UBIFS print scary error messages only in
    real cases, which are not recoverable. It adds 'quiet' argument
    to the 'ubifs_scan()' function, so the caller may ask 'ubi_scan()'
    not to print error messages if the caller is able to do recovery.

  • 746103aca   UBIFS: inline one-line functions ... Browse Code »

    'ubifs_get_lprops()' and 'ubifs_release_lprops()' basically wrap
    mutex lock and unlock. We have them because we want lprops subsystem
    be separate and as independent as possible. And we planned better
    locking rules for lprops.

    Anyway, because they are short, it is better to inline them.

  • 948cfb219   UBIFS: add a print, fix comments and more minor stuff ... Browse Code »

    This commit adds a reserved pool size print and tweaks the
    prints to make them look nicer.

    It also fixes and cleans-up some comments.

    Additionally, it deletes some blank lines to make the code look
    a little nicer.

    In other words, nothing essential.
