Currently, ufs write support have two sets of problems: work with files and work with directories. This series of patches should solve the first problem. This patch is similar to http://lkml.org/lkml/2006/1/17/61 this patch complements it. The situation the same: in ufs_trunc_(not direct), we read block, check if count of links to it is equal to one, if so we finish cycle, if not continue. Because of "count of links" always >=2 this operation cause infinite cycle and hang up the kernel.
