Hi guys,
Just to let you know you may have turned sizeof(struct dentry) into
something nasty with 64 bit spinlocks (like 200 bytes) which would
mean a significant number (~half?) of dentries will cover 3 cachelines
instead of 2.
If I'm nost mistaken, this would probably be worth correcting.
Thanks,
Nick
