Last time we dicsussed this you pointed out that reserving more lowmem from highmem-capable allocations may actually *help* things. (Tries to remember why) By reducing inode/dentry eviction rates? I asked Martin Bligh if he could test that on a big NUMA box but iirc the results were inconclusive. Maybe it just won't make much difference.

Documentation/filesystems/proc.txt ;) I'll cook something up for that. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
