Artem Bityutskiy a28ad42a4a UBIFS: fix mounting problems after power cuts ... This is a bugfix for a problem with the following symptoms: 1. A power cut happens 2. After reboot, we try to mount UBIFS 3. Mount fails with "No space left on device" error message UBIFS complains like this: UBIFS error (pid 28225): grab_empty_leb: could not find an empty LEB The root cause of this problem is that when we mount, not all LEBs are categorized. Only those which were read are. However, the 'ubifs_find_free_leb_for_idx()' function assumes that all LEBs were categorized and 'c->freeable_cnt' is valid, which is a false assumption. This patch fixes the problem by teaching 'ubifs_find_free_leb_for_idx()' to always fall back to LPT scanning if no freeable LEBs were found. This problem was reported by few people in the past, but Brent Taylor was able to reproduce it and send me a flash image which cannot be mounted, which made it easy to hunt the bug. Kudos to Brent.
