2009-09-17UBIFS: fix debugging dumpArtem Bityutskiy
In 'dbg_check_space_info()' we want to dump current lprops statistics, but actually dump old statistics. Fix this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-09-15UBIFS: improve lprops dumpArtem Bityutskiy
Improve 'dbg_dump_lprop()' and print dark and dead space there, decode flags, and journal heads. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-09-15UBIFS: improve journal head debugging printsArtem Bityutskiy
Convert the journal head integer into the head name when printing debugging information. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2009-09-10UBIFS: do not print scary error messages needlesslyArtem Bityutskiy
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.

2009-01-26UBIFS: add re-mount debugging checksArtem Bityutskiy
We observe space corrupted accounting when re-mounting. So add some debbugging checks to catch problems like this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: print debugging messages properlyArtem Bityutskiy
We cannot use ubifs_err() macro with DBGKEY() and DBGKEY1(), because this is racy and holding dbg_lock is needed. Use dbg_err() instead, which does have the lock held. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: fix checkpatch.pl warningsArtem Bityutskiy
These are mostly long lines and wrong indentation warning fixes. But also there are two volatile variables and checkpatch.pl complains about them: WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gc_seq; WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gced_lnum; Well, we anyway use smp_wmb() for c->gc_seq and c->gced_lnum, so these 'volatile' modifiers can be just dropped.

2008-12-03UBIFS: add debugfs supportArtem Bityutskiy
We need to have a possibility to see various UBIFS variables and ask UBIFS to dump various information. Debugfs is what we need. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-03UBIFS: separate debugging fields outArtem Bityutskiy
Introduce a new data structure which contains all debugging stuff inside. This is cleaner than having debugging stuff directly in 'c'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-11-06UBIFS: fix compilation warningsArtem Bityutskiy
We print 'ino_t' type using '%lu' printk() placeholder, but this results in many warnings when compiling for Alpha platform. Fix this by adding (unsingned long) casts.
