[GitHub] [incubator-nuttx] gustavonihei opened a new pull request #3069: fs/mmap: Clarify MAP_PRIVATE dependency on CONFIG_FS_RAMMAP

gustavonihei opened a new pull request #3069:
URL: https://github.com/apache/incubator-nuttx/pull/3069


   ## Summary
   This MR intends to fix a misleading reported error when `mmap` is called with the MAP_PRIVATE flag and CONFIG_FS_RAMMAP is not enabled.
   
   A simple refactor on `fs_mmap.c` makes this dependency explicit.
   
   ## Impact
   No actual control flow change to the `mmap` function. When CONFIG_DEBUG_FEATURES is enabled, it will not report a ENOSYS error for `mmap` calls with MAP_PRIVATE flag and CONFIG_FS_RAMMAP not defined.
   
   ## Testing
   LTP tests on ESP32 and ESP32-C3.
