Based on code reading ...
1. iput() gets inode_lock (a spin lock)
2. iput() calls iput_final()
3. iput_final() calls filesystem drop_inode(), followed by 
generic_drop_inode()
4. generic_drop_inode() unlock inode_lock after doing all sorts of fun 
things with the inode

So look to me that generic_drop_inode() statement within 
gfs_drop_inode() should be removed. Otherwise you would get double 
unlock and double list free.

In short, *remove* line #73 from gfs-kernel/src/gfs/ops_super.c in your 
source and let us know how it goes.
