Kent Overstreet	4409b8081d	bcachefs: Repair pass for scanning for btree nodes ... If a btree root or interior btree node goes bad, we're going to lose a lot of data, unless we can recover the nodes that it pointed to by scanning. Fortunately btree node headers are fully self describing, and additionally the magic number is xored with the filesytem UUID, so we can do so safely. This implements the scanning - next patch will rework topology repair to make use of the found nodes. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>	2024-04-03 14:44:18 -04:00
