UBIFS: rename random32() to prandom_u32()

2013-01-15T13:45:27+00:00

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: remove Kconfig debugging option

2012-05-16T16:53:46+00:00

Have the debugging stuff always compiled-in instead. It simplifies maintanance
a lot.

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.

UBIFS: harmonize znode flag helpers

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

We have 3 znode flags: cow, obsolete, dirty. For the last flag we have a
'ubifs_zn_dirty()' helper function, but for the other 2 flags we use
'test_bit()' directly.

This patch makes the situation more consistent and introduces helpers for the
other 2 flags: 'ubifs_zn_cow()' and 'ubifs_zn_obsolete()'.

UBIFS: remove dead code

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

Remove dead pieces of code under "if (c->min_io_size == 1)" statement -
we never execute it because in UBIFS 'c->min_io_size' is always at least 8.
This are leftovers from old pre-mainline prototype.

UBIFS: make force in-the-gaps to be a general self-check

2011-05-13T16:23:54+00:00

UBIFS can force itself to use the 'in-the-gaps' commit method - the last resort
method which is normally invoced very very rarely. Currently this "force
int-the-gaps" debugging feature is a separate test mode. But it is a bit saner
to make it to be the "general" self-test check instead.

This patch is just a clean-up which should make the debugging code look a bit
nicer and easier to use - we have way too many debugging options.
