Subject: btr_slice_out_node(): Set parent to NULL.
X-Git-Tag: v0.4.11~24
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=6b28eee0756dff0e5dae8d2c1292a0be097706dd;p=paraslash.git

btr_slice_out_node(): Set parent to NULL.

Without this, a subsequent btr_remove_node() on the spliced
out node could segfault.
