NAME

       typedef journal_t - The journal_t maintains all of the journaling state
       information for a single filesystem.

SYNOPSIS

       typedef journal_t;

DESCRIPTION

       journal_t is linked to from the fs superblock structure.

       We use the journal_t to  keep  track  of  all  outstanding  transaction
       activity  on the filesystem, and to manage the state of the log writing
       process.

       This is an opaque datatype.
