New Revision: 222954
URL: http://svn.freebsd.org/changeset/base/222954

Log:
   - If the fsync in ufs_direnter fails SUJ can later panic because we have
     partially added a name.  Allow ufs_direnter() to continue in the
     hopes that it is a transient error.  If it is not, the directory
     is corrupted already from IO errors and writing this new block
     is not likely to make things worse.
