Hi,
I too tested to stress the new VM Quintelas mmap002 "deadlocks" for me. PPro, 96 MB, UP
active: 22337 (I think this varies, have too lock a 2nd time) inactive_dirty: 324 varies inactive_clean: 0 free: 288 ... 1x 512 = 512 kB ... 2 x 16 + 1 x 32 + 1 x 64 = 640 kB
My feeling when looking at Alt-SysRq-M was that pages was moved between Active and idle_dirty - will look into this.
There is no 'if (current->need_resched) schedule()' in this code - if kswapd starts too loop...
PS Now I am back from my vacation period... DS
