[Minios-devel] [UNIKRAFT PATCH 00/22] import vfs from OSv

[Yuri Volchkov <yuri.volchkov@xxxxxxxxx>]

This series is an initial import. I tryied to keep ammount of
modifications small. And failed.

Series has a lot of style problems. But fixing style would blow it
even more. I will provide follow-ups cleaning up this mess.

And sorry for the patch sizes. At least these huge patches contain only
mechanical modifications (e.g. new -> malloc, delete -> free,
replacing OSv functions with Unikraft analogues). I hope this helps.

Depends on:
 - introduce strlcpy and strlcat
 - minor mutex update
 - introduce ukarch_dec
