Subject: buffer_tree: Assert that we don't pass NULL to memcpy().
X-Git-Url: https://git.tuebingen.mpg.de/?a=commitdiff_plain;h=24c1b93962fc54d716d15ec914f6ca35b4b50b8b;p=paraslash.git

buffer_tree: Assert that we don't pass NULL to memcpy().

The buffer pointer cannot be NULL here because this only happens when the
buffer tree area is full, which is not the case thanks to the previous n <=
btr_pool_unused(btrp) check.
