From 2a00e1e5c7b880e4a6529c12749965064195e478 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Thu, 28 Apr 2016 10:40:09 +0200 Subject: [PATCH] udf: Export superblock magic to userspace Currently UDF superblock magic doesn't appear in any userspace header files and thus userspace apps have hard time checking for this fs. Let's export the magic to userspace as with any other filesystem.
