X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4cc7c2734e2b4032103e47d8f3e8b6fa3360d3f1;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [ROSE]: Fix routing table locking in rose_remove_neigh. The locking rule for rose_remove_neigh() are that the caller needs to hold rose_neigh_list_lock, so we better don't take it yet again in rose_neigh_list_lock.
