Andriy Gapon 694a0a8717 zfs arc_reclaim_thread: no need to call arc_reclaim_needed when ... resetting needfree needfree is checked at the very start of arc_reclaim_needed. This change makes code easier to follow and maintain in face of potential changed in arc_reclaim_needed. Also, put the whole sub-block under _KERNEL because needfree can be set only in kernel code. To do: rename needfree to something else to aovid confusion with OpenSolaris global variable of the same name which is used in the same code, but has different meaning (page deficit). Note: I have an impression that locking around accesses to this variable as well as mutual notifications between arc_reclaim_thread and arc_lowmem are not proper.
