2013-03-20 Thread Mel Gorman
The following problem was reported against a distribution kernel when zone_reclaim was enabled but the same problem applies to the mainline kernel. The reproduction case was as follows 1. Run numactl -m +0 dd if=largefile of=/dev/null This allocates a large number of clean pages in node 0 2.

The following problem was reported against a distribution kernel when zone_reclaim was enabled but the same problem applies to the mainline kernel. The reproduction case was as follows 1. Run numactl -m +0 dd if=largefile of=/dev/null This allocates a large number of clean pages in node 0 2.
