fs/procfs README
================
This is a tiny procfs file system that allows read-only access to a few
attributes of a task or thread. This tiny procfs fs file system can be
built into the system by enabling:
CONFIG_FS_PROCFS=y
It can then be mounted from the NSH command like like:
nsh> mount -t procfs /proc
