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

[Simon Goldschmidt]

Follow-up Comment #14, patch #5453 (project lwip):

OK, you're right about existing ports. But at least we need some serious
documentation that SYS_LIGHTWEIGHT_PROT==0 means no protection at all!

And besides, I think at least we can throw away the code in pbuf.c for
SYS_LIGHTWEIGHT_PROT==0 (the u8_t used to 'lock' and the pbuf_pool_free_sem
which locks 2 calls to pbuf_free() against each other, which shouldn't happen
with our new view of SYS_LIGHTWEIGHT_PROT==0)
