[lwip-devel] RFC: SYS_ARCH_DECL_PROTECT makes no sense, remove it

[Leon Woestenberg]

Hello,

the SYS_ARCH_DECL_PROTECT protection mechanism makes
no sense to me. It never did.

It protects pbuf->ref count against concurrent read-write-modify
actions, alright.

But as the rest of the pbuf fields and code is not protected against 
concurrent use (let alone the rest of the lwIP core) I see no real
world use of it.

RFC: Remove this from the stack.

Regards,

Leon.
