When writing a new Fastmap the first thing that happens is refilling the pools in memory. At this stage it is possible that new PEBs from the new pools get already claimed and written with data. If this happens before the new Fastmap data structure hits the flash and we face power cut the freshly written PEB will not scanned and unnoticed. Solve the issue by locking the pools until Fastmap is written. Cc: <stable@vger.kernel.org> Fixes: dbb7d2a8 ("UBI: Add fastmap core") Signed-off-by:
