From 8de52778798fe39660a8d6b26f290e0c93202761 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 6 Feb 2012 12:45:27 -0500 Subject: vfs: check i_nlink limits in vfs_{mkdir,rename_dir,link} New field of struct super_block - ->s_max_links. Maximal allowed value of ->i_nlink or 0; in the latter case all checks still need to be done in ->link/->mkdir/->rename instances. Note that this limit applies both to directoris and to non-directories.
