 .SH DESCRIPTION
-.LP
 The \fBepoll_create()\fR and \fBepoll_create1()\fR functions both create an
 \fBepoll\fR(5) instance that can be operated upon via \fBepoll_ctl\fR(3C),
 \fBepoll_wait\fR(3C) and \fBepoll_pwait\fR(3C).  \fBepoll\fR instances are
 represented as file descriptors, and should be closed via \fBclose\fR(2).

 .SH NOTES
-.LP
-
 The \fBepoll\fR(5) facility is implemented for purposes of offering
 compatibility for Linux-borne applications; native
 applications should continue to prefer using event ports via the
 \fBport_create\fR(3C), \fBport_associate\fR(3C) and \fBport_get\fR(3C)
 interfaces.  See \fBepoll\fR(5) for compatibility details and restrictions.
