Is JFFS a full featured filesystem?

Hmmm. I didn't really expect it to work without deadlocking - I expected
there to be some path from jffs_write_node() through jffs_fmalloc() to
jffs_garbage_collect() and hence jffs_rewrite_data() - which would attempt
to obtain the lock for a second time.

In fact, it seems that it does work, because there's no attempt made to
trigger immediate GC if jffs_write_node() finds that there's not enough
space. Am I on crack or is this really the case?
