[lwip-devel] [bug #50838] mem.c needs SYS_ARCH_PROTECTION around MEM_STATS

[Daniel Elstner]

Follow-up Comment #4, bug #50838 (project lwip):

I just had a look at the code in mem.c which uses these macros and I noticed
that these increments/decrements are already protected by a mutex -- at least
if MEM_LIBC_MALLOC is 0.

So I think it might be preferable to have the extra locks only where needed,
and change the MEM_STATS macros back to unlocked.
