Malloc has its own mutex, however when it needs to do page allocations via kmem_malloc() it drops the mutex and calls it. kmem_malloc() needs giant. what do I do? Do I grab giant before calling malloc(9)? Do I make malloc(9) aquire or recurse on giant automatically? (basically grab giant around kmem_malloc() call in malloc(9)) ? -- -Alfred Perlstein [alfred@freebsd.org] 'Instead of asking why a piece of software is using "1970s technology," start asking why software is ignoring 30 years of accumulated wisdom.'
