From: Alexander Gordeev <hidden>

Also in:
linux-ide, linux-mips, linux-pci, linux-rdma, linux-s390, linux-scsi, linuxppc-dev, lkml
Subsystem:
qlogic qla2xxx fc-scsi driver, scsi subsystem, the rest · Maintainers:
Nilesh Javali, "James E.J. Bottomley", "Martin K. Petersen", Linus Torvalds
As result of recent re-design of the MSI/MSI-X interrupts enabling pattern this driver has to be updated to use the new technique to obtain a optimal number of MSI/MSI-X interrupts required.
