Re: [Minios-devel] [UNIKRAFT PATCH 2/4] lib/posix-libdl: Import dlfcn.h from musl

[Felipe Huici <Felipe.Huici@xxxxxxxxx>]

Hi,

This patch looks good, thanks.

-- Felipe

Reviewed-by: Felipe Huici <felipe.huici@xxxxxxxxx>

    Copied as is from the official musl git mirror
    git://git.musl-libc.org/musl, commit 6fcb440d.
    
    Original file locations:
    * include/dlfcn.h
    
    It's not important where we copy these declarations from given that we 
intend
    to use only stubs. We chose musl only for consistency with previous code 
imports.
