From a3816ab0e8fe542a89a53b82506a8ddac063fbe3 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 29 Sep 2014 16:08:25 -0700 Subject: fs: Convert show_fdinfo functions to void seq_printf functions shouldn't really check the return value. Checking seq_has_overflowed() occasionally is used instead. Update vfs documentation.
