need to.
* sched/sched_waitid.c and sched_wait.c: Add support for waitid()
and wait(). See issues with waitpid() above.
* include/nuttx/fs/fs.h and fs/fs_files.c: Add a dup() method to
the struct mountpt_operations. When dup'ing a file that resides
on a mounted volume, let the file system's dup() method do the
work.
* fs/romfs/fs_romfs.c: Implemented the dup() method for the ROMFS
file system.
* fs/fat/fs_fat32.c, fs/nxffs/nxffs_initialize, and
fs/nfs/nfs_vfsops.c: Add hooks for dup() method (not yet
implemented).
* fs/romfs: Remove the rf_open flag. It looks good, but actually
does nothing.
