This is used by some fanotify listeners which need to scan files before allowing the system access to use those files. This is used by some anti-malware vendors and by some hierarchical storage managent systems. If unsure, say N. t.cgi/'>index : net-next.git

PCI/MSI: Don't apply affinity if there aren't enough vectors left
Bart reported a problem wіth an out of bounds access in the low-level IRQ affinity code, which we root caused to the qla2xxx driver assigning all its MSI-X vectors to the pre and post vectors, and not having any left for the actually spread IRQs. Fix this issue by not asking for affinity assignment when there are no vectors to assign left.
