2009-09-15UBIFS: improve journal head debugging printsArtem Bityutskiy1-7/+8

2009-09-10UBIFS: do not print scary error messages needlesslyArtem Bityutskiy1-1/+1
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.

2008-08-13UBIFS: increment commit number earlierArtem Bityutskiy1-1/+1
Increment the commit number at the beginnig of the commit, instead of doing this after the commit. This is needed for further optimizations. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-08-13UBIFS: ensure UBIFS switches to read-only on errorAdrian Hunter1-0/+2
UBI transparently handles write errors by automatically copying and remapping the affected eraseblock. If UBI is unable to do that, for example its pool of eraseblocks reserved for bad block handling is empty, then the error is propagated to UBIFS. UBIFS must protect the media from falling into an inconsistent state by immediately switching to read-only mode. In the case of log updates, this was not being done.
