sys/sys : file.h filedesc.h
Log message:
Update the file reference count field `f_count' using atomic operations
instead of using a mutex for update serialization. Use a per-fdp mutex
to manage updating of file instance pointers in the `fd_ofiles' array
to let fd_getfile() acquire file references safely with concurrent file
reference releases.
