+ * 2. We re-mount R/W, which makes UBIFS to read the "lsave"

+ * categories ('ubifs_remount_fs()' -> 'ubifs_lpt_init()'
+ * -> 'lpt_init_wr()' -> 'read_lsave()' -> 'ubifs_lpt_lookup()'
+ * -> 'ubifs_get_pnode()' -> 'update_cats()'
+ * -> 'ubifs_add_to_cat()').
+ * 3. Lsave contains a freeable eraseblock, and @c->freeable_cnt
