   HI,
   
   The file names listed under the /proc/fs/ directory are missing the last 
letter when using the 'ls' command.  Operations on the files themselves however 
must include the missing/unknown letter. This is occurring both on-target and 
QEMU.  Details of Nuttx build are as follows:
   
   * Toolchain: riscv64-unknown-elf-gcc-8.3.0-2019.08.0-x86_64-linux-ubuntu14
   * Nuttx GIT version: 
https://github.com/apache/nuttx/commit/f4683713327aaeab0656e3ea83814b44267bdc4a
   * Built with commands:
   `
   $ make distclean -j16
   $ ./tools/configure.sh rv-virt:knsh64
   $ make -j16
   $ make export -j16
   $ make import -j16
   `
   * Executed with command:
   `
   $ qemu-system-riscv64 -semihosting -M virt,aclint=on -cpu rv64 -smp 8 -bios 
none -kernel nuttx -nographic -serial mon:stdio
   `
   
   Below is a capture of the terminal log to demonstrate the issue:
   
   `
   nsh> ls /proc/fs
   /proc/fs:
    block
    moun
    usag
   nsh> cat /proc/fs/moun
   nsh: cat: Could not open /proc/fs/moun (is procfs mounted?)
   nsh: cat: open failed: 2
   nsh> cat /proc/fs/mount
     /proc type procfs
     /system type hostfs
   `
