      UBIFS: extend debug/message capabilities · 235c362b
      Sheng Yong authored
      In the case where we have more than one volumes on different UBI
      devices, it may be not that easy to tell which volume prints the
      messages.  Add ubi number and volume id in ubifs_msg/warn/error
      to help debug. These two values are passed by struct ubifs_info.
      
      For those where ubifs_info is not initialized yet, ubifs_* is
      replaced by pr_*. For those where ubifs_info is not avaliable,
      ubifs_info is passed to the calling function as a const parameter.
      
      The output looks like,

      UBIFS: introduce helper functions for debugging checks and tests · 2b1844a8
      Artem Bityutskiy authored
      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.

      UBIFS: use correct flags in lprops · 37662447
      Artem Bityutskiy authored
      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.

      UBIFS: allocate scanning buffer on demand · cd5f7485
      Artem Bityutskiy authored
      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.

      UBIFS: do not print scary error messages needlessly · 348709ba
      Artem Bityutskiy authored
      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.
