Subject: bcachefs: Don't use BTREE_ITER_INTENT in make_extent_indirect()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3997989ae1541dea4bb144bd2bf8b7dc6cae743f;p=linux.git

bcachefs: Don't use BTREE_ITER_INTENT in make_extent_indirect()

This is a workaround for a btree path overflow - searching with
BTREE_ITER_INTENT periodically saves the iterator position for updates,
which eventually overflows.
