[Cluster-devel] [PATCH] GFS2: fix code parameter error in inode_go_lock

[Bob Peterson <rpeterso@redhat.com>]

----- Original Message -----
| In inode_go_lock() function, the parameter order of list_add() is error.
| According to the define of list_add(), the first parameter is new entry
| and the second is the list head, so ip->i_trunc_list should be the
| first parameter and the sdp->sd_trunc_list should be second.
