ufs_trunc_branch(): massage towards killing recursion
We always have 0 < depth2 <= depth in there, so if (--depth) { if (--depth2) A B } else { C // not using depth2 } D // not using depth2 is equivalent to if (--depth2) A with s/depth/depth - 1/ if (--depth) B else C D Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
