JFFS2 LOCKING DOCUMENTATION
---------------------------
correspondent jffs2_inode_cache object). So, the inocache_lock
has to be locked while walking the c->inocache_list hash buckets.
+This spinlock also covers allocation of new inode numbers, which is
+currently just '++->highest_ino++', but might one day get more complicated
+if we need to deal with wrapping after 4 milliard inode numbers are used.

Note, the f->sem guarantees that the correspondent jffs2_inode_cache
will not be removed. So, it is allowed to access it without locking
the inocache_lock spinlock.
