When the debugging self-checks are enabled, we go trough whole file-system after mount and check/validate every single node referred to by the index. This is implemented by the 'dbg_check_filesystem()' function. However, this function fails if we mount "unclean" file-system, i.e., if we mount the file-system after a power cut. It fails with the following symptoms: UBIFS DBG (pid 8171): ubifs_recover_size: ino 937 size 3309925 -> 3317760 UBIFS: recovery deferred UBIFS error (pid 8171): check_leaf: data node at LEB 1000:0 is not within inode size 3309925 The reason of failure is that recovery fixed up the inode size in memory, but not on the flash so far. So the value on the flash is incorrect so far, and would be corrected when we re-mount R/W. But 'check_leaf()' ignores this fact and tries to validate the size of the on-flash inode, which is incorrect, so it fails. This patch teaches the checking code to look at the VFS inode cache first, and if there is the inode in question, use that inode instead of the inode on the flash media. This fixes the issue.
