vm_page_sleep_busy(9)

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.
