UBIFS: extend debug/message capabilities

2015-03-25T09:08:41+00:00

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: rename random32() to prandom_u32()

Use more preferable function name which implies using a pseudo-random
number generator.

UBI: Kill data type hint

2012-05-20T17:25:59+00:00

We do not need this feature and to our shame it even was not working
and there was a bug found very recently.
	-- Artem Bityutskiy

Without the data type hint UBI2 (fastmap) will be easier to implement.

UBIFS: rename dumping functions

2012-05-16T16:15:56+00:00

This commit re-names all functions which dump something from "dbg_dump_*()" to
"ubifs_dump_*()". This is done for consistency with UBI and because this way it
will be more logical once we remove the debugging sompilation option.

UBIFS: lessen amount of debugging check types

2011-07-04T07:54:28+00:00

We have too many different debugging checks - lessen the amount by merging all
index-related checks into one. At the same time, move the "force in-the-gap"
test to the "index checks" class, because it is too heavy for the "general"
class.

This patch merges TNC, Old index, and Index size check and calles this just
"index checks".

UBIFS: introduce helper functions for debugging checks and tests

2011-07-04T07:54:28+00:00

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: add few commentaries about TNC

2011-07-04T07:54:27+00:00

Add a couple of comments - while looking into TNC I could not easily figure out
few facts, so it is a good idea to document them in the code.
