vm_page_sleep_busy - "wait for a busy page to become unbusy"
.In vm/vm_page.h int vm_page_sleep_busy "vm_page_t m" "int also_m_busy" "const char *wmesg"
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.
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.
