2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Steven J. Magnani <[email protected]> commit 04c3496152394d17e3bc2316f9731ee3e8a026bc upstream. Depending on processor speed, page size, and the amount of memory a process is allowed to amass, cleanup of a large VM may freeze the system for many seconds. This can result in a watchdog timeout. Make sure other tasks receive some service when cleaning up large VMs. Signed-off-by: Steven J.
