[GitHub] [incubator-nuttx] ALTracer commented on issue #5253: `df -h` not rendered correctly when LIBC_LONG_LONG is disabled

   I can confirm I see similar behaviour of nsh mount printing weird sizes on at least `stm32f072b-disco:nsh` (or tweaked) and a new custom armv6-m platform.
   I certainly did non enable LONG_LONG, because I have really tight ram constraints, and both MCUs are 32-bit, not requiring to survive y2038/time64_t etc.
   I might check it again with a live SWD debugger, considering nsh uses vsnprintf-family functions.
   
   Is the overhead of multiple calls per mountpoint significant (code, stack, execution time)?
