From 1c089c325d5cda0f64a3cf8edf3aaafa148f200a Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 7 Sep 2006 15:50:20 -0400 Subject: [GFS2] Remove one typedef This removes one of the typedefs from the locking interface. It is replaced by a forward declaration of the gfs2 superblock. The other two are not so easy to solve since in their case, they can refer to one of two possible structures.
