VM_PAGE_SLEEP_BUS... MidnightBSD Kernel Developer’s ManualVM_PAGE_SLEEP_BUS...

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.
