NAME
     vm_page_sleep_busy - wait for a busy page to become unbusy


SYNOPSIS
     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/vm_page.h>

     int
     vm_page_sleep_busy(vm_page_t m, int also_m_busy, const char *wmesg);


DESCRIPTION
     The vm_page_sleep_busy() function waits until the PG_BUSY flag is
     cleared.  If also_m_busy is non-zero, it also waits for m->busy to become
     zero.


RETURN VALUES
     If vm_page_sleep_busy() finds the page busy it returns TRUE.  If not, it
     returns FALSE.  Returning TRUE does not necessary mean that
     vm_page_sleep_busy() slept, but only that splvm() was called.
