[PATCH v3 04/24] fs: Add docstrings to exported functions

[Tobin C. Harding]

Currently exported docstrings for fs/file_table.c are included in
Documentation/filesystems/api-summary.rst.  This is a problem because
there are no docstrings in file_table.c

Add function docstrings for exported functions defined in
fs/file_table.c
