- * infrastructure at least.
- *
- * So what is the problem, why we need to drop those nodes? Whey can't

- * only about the GC head, so we could do this trick only if the bud

- * additional "if" statement.
- *
- * So, imagine the file-system is full, we run GC which is moving valid
- * nodes from LEB X to LEB Y (obviously, LEB Y is the current GC head
- * LEB). The @c->gc_lnum is -1, which means that GC will retain LEB X
- * and will try to continue. Imagine that LEB X is currently the
- * dirtiest LEB, and the amount of used space in LEB Y is exactly the
- * same as amount of free space in LEB X.
- *
- * And a power cut happens when nodes are moved from LEB X to LEB Y. We
- * are here trying to recover LEB Y which is the GC head LEB. We find
- * the min. I/O unit B as described above. Then we clean-up LEB Y by
- * padding min. I/O unit. And later 'ubifs_rcvry_gc_commit()' function
- * fails, because it cannot find a dirty LEB which could be GC'd into
- * LEB Y! Even LEB X does not match because the amount of valid nodes
- * there does not fit the free space in LEB Y any more! And this is
- * because of the padding node which we added to LEB Y. The
- * user-visible effect of this which I once observed and analysed is
- * that we cannot mount the file-system with -ENOSPC error.
- *
- * So obviously, to make sure that situation does not happen we should
