The patch titled mm: vmalloc search restart fix has been removed from the -mm tree. Its filename was mm-vmalloc-search-restart-fix.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mm: vmalloc search restart fix From: Glauber Costa <glommer@xxxxxxxxxx> Current vmalloc restart search for a free area in case we can't find one. The reason is there are areas which are lazily freed, and could be possibly freed now. However, current implementation start searching the tree from the last failing address, which is pretty much by definition at the end of address space. So, we fail. The proposal of this patch is to restart the search from the beginning of the requested vstart address. This fixes the regression in running KVM virtual machines for me, described in http://lkml.org/lkml/2008/10/28/349, caused by commit db64fe02258f1507e13fe5212a989922323685ce.
