jffs2: Improve post-mount CRC scan efficiency
We need to finish doing the CRC checks before we can allow writes to happen, and we currently process the inodes in order. This means a call to jffs2_get_ino_cache() for each possible inode# up to c->highest_ino. There may be a lot of lookups which fail, if the inode# space is used sparsely. And the inode# space is *often* used sparsely, if a file system contains a lot of stuff that was put there in the original image, followed by lots of creation and deletion of new files. Instead of processing them numerically with a lookup each time, just walk the hash buckets instead. [fix locking typo reported by Dan Carpenter] Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
