NAME

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

DESCRIPTION

       The  vm_page_sleep_if_busy()  function  waits until the VPO_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_if_busy() finds the page busy it returns TRUE.  If not,  it  returns  FALSE.   Returning
       TRUE does not necessary mean that vm_page_sleep_if_busy() slept, but only that splvm() was called.
