Subject: bcachefs: node scan: ignore multiple nodes with same seq if interior
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fabb4d49854281027454b0fa305d33f6c9ec4b47;p=linux.git

bcachefs: node scan: ignore multiple nodes with same seq if interior

Interior nodes are not really needed, when we have to scan - but if this
pops up for leaf nodes we'll need a real heuristic.
