[lwip-devel] [patch #5453] pbuf patch for SYS_LIGHTWEIGHT_PROT=0

[Jonathan Larmour]

Follow-up Comment #12, patch #5453 (project lwip):

I'm not sure there's an imperative to change the name (and consequently break
existing ports).

I think it's called "lightweight" because it's a simple and direct way to
protect critical regions. Other solutions could also be implemented which
could cause less system disturbance and work at a finger granularity, but
they would not be as simple/lightweight.

It's possible someone might come up with an alternative more complex
implementation at some point, in which case SYS_LIGHTWEIGHT_PROT==1 reflects
this particular implementation, to allow existing ports to work.
