Data structure to fix slow write/append to files on ramfs

I am planning to take a stab at fixing https://github.com/cloudius-systems/osv/issues/884. As explained in the issue, possible solution would require data structure supporting efficient read from and write to the file as well as memory allocation. One candidate is std::deque. Another

[PATCH 06/16] bsd: Added IPv6 net channel support

classifier changed to object pointer instead of embedded in struct ifnet to reduce compile dependencies. There was also issue with including ip6.h in this file, but that could probably be fixed with struct ip6_hdr forward delcaration and including in6.h instead. Signed-off-by: Charles Myers ---

Thanks. So fundamentally you think this patch is OK? Even possible memory misalligment is not a big deal? On Monday, August 6, 2018 at 10:48:46 AM UTC-4, Nadav Har'El wrote: > > > On Wed, Aug 1, 2018 at 7:48 AM, Waldemar Kozaczuk > wrote: > >> This patch optimizes RAM utilization of bootfs by
